You are the person I think of all the time.

You are always on my mind.

You make me smile.

You make me happy.

You always make me laugh.

Everything about you is wonderful, whether it's your looks, your humor, your way of speaking, your laugh, the way your eyes crease when you look at me and smile, the way your smile is lopsided or the way you do the most random and amazing things.

You are special to me.

This is what people in the UK used to say before the arrival of the ubiquitous "There you go!" from the US. It is what is said by a cashier at the checkout when they return your credit card, by the waiter when they bring a you a meal, etc etc. It doesn't really mean much, it's an acknowledgement more than anything. Sometimes "Here you are!" is substituted for "There you are!".

The person you shouldn't be afraid to be, someone you should be proud of.

Well known

slang for "you are". commonly used by uneducated people, street people, rappers and pimp

The perfect comeback to any insult.

Means something special for giving to someone
