Nobody is sneering but if someone writes 'would of' and someone else points out it is 'would have', then they get all defensive. There are a lot of things I know little about and I'm happy to be corrected so that I don't make that mistake in the future.
See this is what I don't understand.
Most people here are adults, who will have had at least 11 or 12 years of schooling as a minimum.
They will have been taught that at school. They will no doubt have been reminded at some point since leaving school. They will have repeatedly read the words 'would have' in books/news reports/when helping with DC's homework.
So why on earth do some Mumsnetters think that they are going to be that one person, who 'makes a difference' by pulling that person up on an internet chat forum?
Do they really think they're so special, that the person will suddenly remember it for evermore, because a random name on the internet has told them it's would have?
No, imo it's far more about the fact some people won't take responsibility for their own irritability when they see other people using poor grammar.
It's all about them and not the person they claim to be 'helping'.
I also think this sort of thing (being done to death) probably puts a lot of lurkers off of posting here for support, because they may worry their grammar is not up to scratch and they don't want to embarrass themselves.
Shame, considering Mumsnet should be for anyone who needs it.
