It never fails

[trickykitty]

I know "their" is possessive, and I know "they're" is short for "they are". I know when it's wrong when I'm reading something. It sticks out like a sore thumb.

So then, why the hell can't I get it right when I'm actually in the process of typing something out. I'm ALWAYS having to go back and correct myself after the fact, and it's annoying as hell.
