What's you're pet peeve?

^That's mine.
It's not that complicated, English isn't my first language either, just learn it.

Pronoun = Your
You are = You're

You're pretty. 
Your pretty face. 
Got it?

Thank you for your time, I hope you're appreciating the fact everyone can now use proper grammar, at least when it comes to your vs. you're.
