My Language Pet Peeve

It truly bothers me when people don't know the difference between the words: there, their, and they're. Oooo...it bugs me. I understand that either they weren't paying attention when this was taught OR they truly don't know or remember how it works. So here it is for all those who need a quick lesson. 'There' refers to over 'there' or 'There it is'. 'Their' refers to possession of something, like 'their' hat, 'their' coat, etc. 'They're is a contraction that means 'they are'.
