Three things

I have a long list, but top three might be.....

Swearing and bad manners - not sayjng please, thank you, excuse me etc.

Parents who use their kids buggies like a battering ram on the pavements and expect everyone else to move out of their way.

The use of 'text speak/spelling' in emails, letters, blog posts etc. It's invariably unintelligible and just sheer lazy.

Ooh I could go on and on........

1)older people who are perfectly fit sitting in priority seats for the disabled (age in itself is not a disabiity ) 2) people who park in disabled bays without a blue badge and3) disabled loos which double as baby changing rooms There seems to be a theme here !

In no particular order:-

People who say "of" instead of "have"

Those self centred individuals who think they're the only ones with illness, aches & pains and the very worst medical conditions known to man!

People who dismsis all and every suggestions of meal planning, what to do with leftovers, look a gift horse in the mouth and act out the "poor me" scenario ALL THE TIME!

1. People talking VERY LOUDLY on their mobiles in the hairdressers/supermarket
2. People who assume because you speak with a cockney accent you must be a) thick b) uneducated c) live in a high rise council flat - the class system is alive and well, or it was when I left London 9 years ago. Same goes for regional accents as well.
3. People talking to me when I'm in the middle of a complicated spreadsheet, Grrrrrr, "bog off"!
Am I allowed 4? People who don't flush the toilet and don't wash their hands. Nothing worse than going into a public loo and coming face to face with a log! Yuk

Drivers who assume that everybody knows where they are going and never bother to indicate.

People who never say ‘please’ or ‘thankyou’.

People who have a phone conversation while they are being served in a shop.

People who put up posters for events and don't remove them afterwards.
Pedal bin liners that are just that wee bit too small.
Tights that never fit

Pretty much all of the above, but I do swear.
Lazy, useless colleagues who seem to get away with it and get promotions!
Stupid people with lack of knowledge

Parents on long mobile phone conversations who tell their children to 'shut up, can't you see I'm on my phone '.

Children and grandchildren who only ring you to ask if you will transfer money to their account.

Interviewees who, when asked to explain something or give an opinion, start every reply with 'So..'

Parents generally giving their children too much choice over everything from what they want to eat, wear, do etc. to how things should be done. No wonder there is so little respect for 'rules' !

Dogs off lead that come steaming up to my (slightly nervous) on-lead greyhound, resulting in my arm being wrenched as she tries to avoid them. This is ok though, as they 'only want to play'.

Sorry, I just have to add this one after reading her commments from Beteljus about dogs; those dog walkers who use those extendable dog leads when walking on the pavements! How inconsiderate can you get????? I recently had to walk in the road because this stupid woman was on the outer edge of the pavement and her dog was on an extended lead on the inner edge of the same pavement, no one could get past without getting tangled up! Bloody moron!

Hetty58 good thing you don't live here in France, tail gating is a national pastime

I'm with you there peardrop slim, elegant women are on my list too.

The mispronunciation of words; it’s privacy not pryvacy.
Pants meaning trousers, pants are underwear.
People who ‘use’ the benefits system when they have no right to making it harder for those who really do need support.
Depressing news reports EVERY day. Is there no good news?

Sorry that’s 4 but I was on a roll

Not sure three items is enough!

1. Animal cruelty

2. Talking loudly and pacing up and down when talking on their mobiles.

3. Someone who takes a phone call when I am visiting them and continues the conversation for which seems forever (mainly about medical issues) while I have to sit and appear to not be listening which is impossible.

People talking about their ailments all the time, and using them as an excuse for not doing things that they could.
Anybody who can’t hear and appreciate that there are always at least two sides to every argument, and repeating your view loudly without listening doesn’t mean you’re right.
Older people who have ‘given up’ bothering about their appearance and approach to others, and don’t engage fully in the world of now, as that’s what makes us all invisible - you’ve got to be in it to win it I think.

1. Bad manners e.g. no please or (especially) thank you
2 Bad speech and grammar. We are not only losing the t in words but, I have noticed, the l in hospital. My pet hate - wrong apostrophes and wrong use of me and I e.g (very common) Gabriella has sent a thread to you and I
3 People not controlling their dogs or picking up their dog mess (not so common now, I admit) or throwing the dog mess bag into the verge or hanging from a tree !

1. Trump
2. Johnson
3. Cummings

Actually, on reflection these people incense me rather than irk ... and I have quite a few more ...?

No 1 Dog owners who let their dogs sh -t on my path and leave it there or throw bags full of dog poo into the trees near my house.
No2 Cyclists who don’t dismount on a narrow path by a ford near me when there is a sign saying No Cycling.
No 3 Shop assistants who drum their fingers on the counter in irritation at my slowness as my arthritic fingers fumble in my purse for coins.

Ok.... number 1 is dropping pegs before I get chance to ping them on the washing line.... grrrrrrr.

Number 2 is the noise of a crisp bag being rustled ... grrrrrrr

Number 3 is people talking over me ! ... grrrrrrr.

Apart from that I would say I am pretty placid about things ..... hahahahahahaha....

1- Hypacondriachs
2- Arrogant gits who think thier opinion is the only one that matters and you absolutely MUST listen to them (Cumberprat being the main one with Emma Thompson not far behind)
3 - Noisy, spoilt brats and thier idiot parents who seem to think thier behaviour is acceptable...

I could go on for hours!

P.S - Agree with just about everyone who has already posted.

Casdon, I like your third paragraph

What irks me the most is appliances bleeping at me. It really does drive me mad
Drivers not indicating. Am I a mind reader?
Judgemental people, who only see things from their point of view. No one really knows what’s happening in people’s lives
It’s not the end of the list, but you only asked for three
