There's a loving difference between them. And I'm tired of people using 'your' instead of 'you're', where 'you're' is needed.
You're is a contraction of 'you' and 'are'
EXAMPLES: You're nice, you're also a grapefruit.
You're an asshat get out.
You're awesome, I love you.
Your is belonging to you, or something.
EXAMPLES: That is yours.
Did you ask your mom?
Yours is different from mine.
Examples of wrong use:your gay
My gay? Excuse me, what?
you'res is blue
You are is blue...?
Hopefully now you get it, because this is just ridiculous.
