That reminds me of the G....
I have to say though... I do use the apostrophe at the wrong times often these days. I think it's because so much of the internet does use it the wrong way... I just kind of blended it in.
I do try to follow all the other rules though.... so as not to be said wanker.
:-)
I do understand the basic uses of the ' though, just as particle said, and I do some times use the comma too much as well... though for me it signifies a pause in my thought or breathing, much like the "..." does.
