I have read a lot since childhood, and I think that's where I've picked up some of good habits, but I'm by no means an expert. I make mistakes all the time and I think my ability has declined, especially in spelling, because of predicative text and spell check functions. I have always struggled with alot and a lot. Your, you're, their, there, and they're are all second nature mostly, I think because I learned (not learnt!) the words first and then the contraction. So I would start with 'You are' and then learned that the apostrophe could be used to shorten the word, removing letters and adding the apostrophe making 'You're'.
However, someone has mentioned the use of "DH and I have been invited to..."
Is this incorrect? I was taught at school to use that rather than "Me and DH", the explanation was that it was 'rude' to put yourself first in the sentence, and secondly using 'me' instead of 'I' was incorrect. I wouldn't even think of using 'myself' as a substitute for 'I' or 'Me'.
I was also taught that names, referring to yourself as I, and after full stops should always be capital letters too. I see lower case 'I' a lot and names written with a starting letter in lower case.
Not really a grammar issue but itch and scratch really pisses me off. I'm not sure if it's a local thing or not.
Person points to patch of red skin
"I've been itching that all day" when they mean they've been scratching it.
Or -
"Look at the dog itching his ear"
The dog is SCRATCHING his ear!!
On a lighter note, this thread has brought to mind a quote I once came across on Facebook about grammar, spelling and the correct use of capital letters being important......
"Helping your uncle jack off a horse"
Translates to
"Helping your Uncle Jack, off of a horse"
I'm not sure the second one is actually correct though
