They're like that in the outside.
You know it's because of their environment at home, they really do tend to express what ever it is they are holding at home in school.
The black (or the ghetto majority) people in my school act the same way. When you get to know them and they spit out their concerns, they are really desperate people trying to get past this ugly stage in life.
White people have acne during pubirty, black people have drugs, gangs, and drop outs.
I've got to say, they still have a hard life.
