Student in sociology

I have never thought about people in there own groups for me the only place seeing them is on tv. Mostly in high school you  really see this maybe as we grow up we see this. In high school I have always been with my some friends this year. We don't really judge people because its not a thing we do usually we just talk about soccer or some stuff we have done. The only time we talk about someone is when we don't its never really something bad we just say the things they have done. We don't judge people for not being like us maybe they have judged us but we don't they are who they want to be.
