Why don't people like me?

Thats just a few people, or a group of people of all the billions of people in the world. I'm sure many many people like you. You sound like you're really nice to me, I'd would be friends with you, and a lot of other people would too. You can't let other people get you down, just keep your head held high and don't care about what people say about you. You need to have a good amount of self-esteem. And if people are laughing, its probably not about you. Say hi to people you've never talked to, always be nice and have a smile on your face.
