Street Smarts

If something isn't taught in a school book, or class, I instantly feel like I won't understand it. Like all the ghetto kids, half the time I don't understand anything they're saying. Or sometimes I don't get what my friends do, and it makes me mad. Maybe they don't have the same common sense level as me? Or does it just simply that we think differently? I have no idea and it really bothers me how sometimes I can't understand why someone does something. But I guess I don't really need to know. Do I? I don't think I do. But it's just nice sometimes
