English grandma (;-)

I find that many youngsters confuse there, their and they're. Affect, effect. Whether, weather. I asked my daughters, now in their 30s, about it (the older one being a teacher) about learning grammar at school and they said that even when they were at school they learnt only literature NOT grammar.

As I said my older daughter is a teacher and I had to teach her about the starting and ending of letters because they weren't taught that, unbelievable when they would be applying for jobs.

E.G.
Dear Sir/Madam Yours faithfully
Dear Mr/Mrs X Yours sincerely

When I get a letter with the wrong start and end invariably it is from a younger person.

The ads that me me chuckle, as well as cringe, are caravans for sale ads, that state whatever number of "births", rather than "berths" in the caravans!

I try not to notice or comment on posts that have errors in spelling and grammar (though I do have a bit of a chuckle if it is on a thread about spelling and grammar), because I would then be completely paranoid about making a mistake myself. As long as people are communicating what they want to say then I think it really doesn't matter too much.
The genre of writing on forums is about speed and response and open-mindedness. When I wrote official reports I checked everything five times; I really don't want to have to do that on here.
(So I promise not to point out that the OP said, 'I must not confuse 'discrete' with 'dscreet')

It's a bit frightening, isn't it? Especially when you've always taken pride in your good spelling and grammar, whatever other failings you may have...

Agree!

Me too... but then my son sent me a very funny cartoon the other day where someone is being patted on the back and the caption says "when I console a grammar nazi I go 'there, they're, their'." . To my horror, lately, I find that I sometimes put an apostrophe in the wrong place, my excuse is, that there are so many mistakes about these days, that I am absorbing them by osmosis and no longer no write from ... sorry know, right from wrong.

And me

Yes I noticed that but chose not to be pedantic again.
I also get irritated by the incorrect use of affect and effect
