My favorite:

You know when you have a crush on someone you don't necessarily like them for the reasons others do. You like them for all the little things they aren't aware of. Like the way they burst out laughing, make weird faces, or dance weirdly. How they act around little kids or the way they move their hair out of their face. They absolutely have no idea of these things. It's the same with you. People watch you and notice all your quirky qualities. You don't notice because you can't see yourself. But others CAN. So when you say you're NOT beautiful or handsome how do you know you're not? You're not the one who sees yourself everyday. You don't see yourself laughing, or acting weird, but to someone, YOU are their definition of perfect.
