I'm mid 30's and have noticed that most of my friends/peers are able to distinguish between 'your and you're', 'where, were, we're' and using the words 'have' and 'of' correctly.
I've noticed that in younger generations there just doesn't seem to be the same standard anymore and I wonder why that is.
Not saying for one minute that my own sp. and grammar is perfect - it isn't. I just wonder if there is as much emphasis on it nowadays as there was back in the day..
