I say be yourself. No one person is representative of an entire race although it seems we blacks get sterotyped the most. I hate when people ask me why do blacks do or not do something like they elected me spokesperson. I have had friends who I was the first black person they had ever known more than in passing. Boy did they ask annoying questions but I tried to open and responsive and they saw I'm just a regular person like them. That is how you destroy sterotypes and not pretending to be someone you're not.
I always use corrrect English when I speak because that is the way I naturally talk. I get flack about it from blacks and non blacks. My white friends tell me I act more white than they do but I'm quick to let them know I'm a black woman. I like many kinds of music. My favorite artist is Sheryl Crow. I went to see her in concert and didn't care about being the only black in the crowd. If you can't be comfortable with yourself it will be hard to make friends because people won't be comfortable around you. Don't let worry rib you of an amazing experience.
