Three things

Mine are
1 cyclists on the pavements, there is a bye law here that forbids it but no action is taken. A few years ago, deaf and blind mil and I were coming out of front gate when older child on bike, on pavement rang his bell to get us to move, hand signals too. I stood there until he went out on the road.

2 ignorant mobile phone users, too loud, I am not interested in their conversations. Also parents ignoring their children when constantly using said phone.

3 parents/grandparents smoking over pushchairs, having no concern where the smoke goes. If you have children, you should look after their well being

People who put things on the internet, thinking Facebook here, about how the world will change because we have all realised how wonderful it is without noise and pollution, the seas will become cleaner and we will all embrace a new way of life....pics of children playing in fields etc. Unrealistic.
People who are very greedy.
People who tip rubbish in the countryside.

Bad language
Opinionated bigots who think that their views are more important than any one else’s
Whole families blocking aisles in supermarkets, why doesn’t one parent take the kids to a park ?

I’m afraid that I have more than 3 but here goes:-

Businesses or companies who say they will phone back and never do.

People who seem intent on talking over me, as if what I have to say is totally unimportant. I used to have a sister in law who did that, oh and the first husband!

Greedy people and those sods who bought hundred of toilet rolls and the last of the hand soap/sanitisers!

There are more but that might get me swearing! Stay safe. X

Lorelei
Number 3 yes totally agree. I know a few people like that...

The constant ranting from husband when the news is on. Not only does he disagree with everything but he makes fun of people's accents.

The fact that he is hard of hearing and denys it. He blames actors on mumbling and the sound quality of modern TV.

The fact he discusses dinner all day long

People who deliberately leave the kitchen in a mess after cooking for me to clear up

People who talk constantly about themselves and their family and aren’t in the slightest bit interested in yours.

People who are ‘know it alls’

1: Reporters that are not remotely articulate and punctuate the whole piece with lots of' er er er er's' + think they are being trendy by filling every sentence with 'like', 'you know', 'basically', 'obviously'....no need to say like, we probably do know more than you, and there was nothing basic or obvious about the piece! Then spend ages badly interviewing irrelevant people.

2: TV programmes that presume we are all so thick and have the attention span of a goldfish, so start each bit of the programme telling you what is coming up, then show 5 minutes, then a section repeating that and saying what is after the break - rinse and repeat 4 or 5 times during a 1-hour programme. Oh, and everything flashes, they can't stay on one image for more than a second, and can't find a cameraman/woman capable of holding the camera still. We don't need bombarding with 60 images a minute, can concentrate on an interview etc and would like steady camerawork and non-repetitive programmes that are not epilepsy-inducing. When will they realise this is not a fantastic filming technique, it is just bloody annoying and gives people headaches and eyestrain. The subject of the programme is often interesting but made bad by these rotten 'techniques'.

3: People that do know better and still have no manners and/or social skills e.g. those who fail to say please, thank you or excuse me - who cough and sneeze (even worse during these Coronavirus times) without covering their face - who use the loo but not the hand-washing facilities - who are all take take take but never give - who are rude for the hell of it - who never have a nice word to say about anything or anyone else...I could go on, but you get the gist I'm sure.

Cold callers are bad enough, but when its a recorded message or no-one there at all, I see red!
People eating with their mouths open especially gum!!
Those who can't be bothered to enunciate properly!! Beau-iful, fink, etc

During lockdown the most annoying (and frightening) thing is other customers ignoring arrows and 2m distancing in shops. They come within inches.

Dog poo not being picked up at anytime and seems worse now I have 3 dogs so do love them and hate being tarred with the same brush as non pick uppers.

Garden bonfires. So many people seem to be having bonfires on sunny days in the middle of the day. Some leave them to smoulder for days. They don’t even check if neighbours have washing out.

By struggle with, I mean trying not to do it myself!

People think other folks business is their own. I lost count of the number of people wanting to know why my daughter got divorced and of those who want to know precise details of why I or others have been unwell. It’s none of their business.

People who call other people ugly or stupid. None of can help what we look like and we’ve all made fools of ourselves.

People who look at the speck in someone else’s eye yet ignore the plank in their own. This is the one I struggle with most of all.

Cyclist illegally riding on pavements
Selfish people ( I'm lucky to have generous friends and hopefully reciprocate!) Not financially but in terms of deeds
People who think that they always know best inc news reporters ( Laura Kuenssberg)

DH who refuses to remember, although I have told him, that I am becoming slightly deaf and cannot hear the radio at the volume he prefers. Likewise that I do not always hear what he says to me.

People who do not answer when you speak to them. How do you know if they actually heard you? I can't make myself address other adults in my best school-marm voice, "Did you hear me? I am waiting for your answer."

People who throw empty beer-cans, sweetie papers and the like over the fence into our garden when walking past.

People writing could of, it is could’ve, an abbreviation of could have.

People who uplift the end of a sentence, I don’t know how best to describe it. For example how the Australians talk, a kind of upswing, as if they are asking a question all the time. My youngest son does it, he is 30, and I am a bit naughty really because I have in the past hummed the tune of Home and Away.

Journalists every day asking, “when will we start to see signs of lockdown lifting?” It reminds me of a child trying to grind a parent down by asking for a new toy every day.
The Prime Minister does not know
The scientists do not know
I do not know!
When things improve, i.e disease and number of infected drastically reduces.
Talk about stating the bl****ng obvious.

Lockdown has turned me into Meldrew.x

If someone’s bag is occupying a seat and the bus/train is filling up ask them to move the bag. Do it politely. People usually respond well.

People who talk loudly, in restaurants, on buses, trains
People who stand in my space and get closer as I move away
People Who volunteer to do things and then never do it

Most of all Journalists who ask the same question over and over without ever bothering to listen to the answer, I have stopped watching Channel 4 News, they are just bullies.

Dog owners who throw full poo bags into the hedge/tree etc or don't pick up at all.

Drivers who don't indicate.

Husbands who don't listen!

I'm with Oopsminty's last comment so my 3 hates are

B
B
C

(ie interviewers especially on the Today programme and Newsnight)

1)People who take a phone call or read a text while they are talking to me face to face OR when they are talking to me on the phone and they stop talking.... to have a conversation with someone who's with them! Both of these make you feel unimportant.
2) People who share things online about covid19 without researching the facts first. Sharing made up, false or exaggerated news on social media or when chatting isn't helping anyone. Read what you've seen or heard being shared, then research it online. ...9/10 times the truth is so much different (and not so scary). Scare mongering is getting ridiculous.
3) Having TV programmes announcing before a pre recorded show that "this was recorded before social distancing was in force". As if we can't work out for ourselves.

People who text others constanly whilst with me. People who walk along looking at their phones. And people who don't say thank you when you hold a door open. I could go on...

Drivers who edge halfway out of a side road into a queue thinking they can bully their way in (nope, but I'll let you out if you are waiting patiently though)

People who are incapable of closkng a cuoboard/drawer and of actually ojtting something they got out back.

People who constantly talk over you when you are speaking. Then saying "sorry for talking over you". No you are not or youbwouldnt keep doing it!

Spot on Sussexborn.

I could easily make a list of 50 things! But - people (usually teenagers) standing on corners in groups and spitting on the ground (even before the virus.)

People with no respect for others and who shout/are foul mouthed/laugh and scream uproariously and flail around etc on buses and trains, or in other public places close to other people.

People who can't discuss something calmly without making it into a screaming argument.

Americans!

Cold callers

DH when he stays up until the early hours & then wants to sleep in for half the morning.
