Honestly, why do people not like others for no reason?

I know exactly how you feel...I try my best to be nice to people..people i dont know but they just stillhave something bad to say about you. Even your presence and them seeing you they'll make something up about u that quick. Its just how some people are. Its also a bit of racism and jealousy. You just have to have tough skin and stick it out. Dont let them get to you and break you because thats all they want.
