They usually are avoiding you or smiling in your face.
Maybe they are, I don't care.. we live in a world that's full of weirdo homebodies that sit around in there little groups and spread rumors and crap.. I have better things to do..
If you're solid in who you are, then things such as people talking crap about you shouldn't even be important enough to know. Don't worry about them, I say. Laugh more and be happy.
If they are really nice to you to your face, or if people treat u a certain way around people
If they shoved food up their butt.
And it was your food. Then, "crap about you" will come out of their mouth.
