Damn autocorrect

I swear my phone hates me and wants me to look retarded. I SWEAR I type everything perfectly. Perfectly spelled, the right words, the right forms of words (your, you're, their, they're, there, etc). I'm a total grammar nazi. And I swear my phone goes right behind me and changes things... To things that don't even make sense! Ugh. But then usually I'm lazy and don't re read it, and just post or send. Then I have to correct everything. It's very very annoying. End rant
