That's true.
Most people are just looking at your appereance. If they don't find you attractive, they don't want to know you. At the other side, if you're attractive in their eyes, they really want to know you, they want to be your friend, and even more than that.
Some of the people are like them, and in my opinion, most of them are jerks.
I hate guys who just looking at girl's face or body. Same thing for the girls.
Attractive or ugly, fat or skinny, it's from God. And we can't judge someone's good or someone's bad just from what he/she look like.
Sometimes, it hurts someone when they be called ugly or fat.
And sometimes, it hurts someone too when someone else be called better than him/herself, even when it's true.
Respect everyone.
Because every human deserves to be respected.
