Why do people tease me for no apparent reason? :(

People are idiots, they don't like those who are different.

Because people are stupid

For unapparent reasons.

Because other can't accept who a person is for what there likes/dislikes are.

They just need someone to tease!
i have always been the subject of scorn scince pre-school -_-

Simple, 당신 have something they really admire/ want. It's either that 또는 they think it's fun to tease 당신 bcos 당신 let it get to you. Try this, whenever any body teases you, laugh with them. They'd get tired and stop.
