I can't take it any more. I could cry. I want to bang my head repeatedly on my desk. Why is it that people don't understand that if the intention is to say 'you are', it's YOU'RE? It's a contraction and the apostrophe represents the missing letter. So for example, 'what do you do with your cat when you're going on holiday?'
If you're not sure which 'your' to use, just ask yourself if you're trying to say 'you are.' Am I alone in my irritation with this? Is it me?
