Well, here's my story. I'm really lazy

and I have been saying for years how I want to go to the gym to tone up, get the legs and thighs in good shape. Now I'm not big, not thick or anything, I am a petite person. I do, however, complain if I have to walk up some stairs or participate in any type of strenuous activity (yes, I consider that strenuous lol).
Soooo, I decided that since I live by the lake I could get some skates and skate on the bike path when spring time hits. It's minutes from my apt, walking, and I figured I would be able to get fresh air and exercise at the same time. My community is diverse and all types of people are along the lake (Hyde Park for you Chicagoans) in the spring and summer. I decided to tell a black male coworker today (I'm black too) and he said: "You always acting like a white girl." I was like

I got so offended. I didn't talk to him for a long while. I refused to discuss the situation with him.
My question is, did I overreact? I mean, should I have been that upset for him saying that to me? I know that you shouldn't take comments like that to heart but it really hurt me. Do you all think that comments like this build someone's character, meaning that someone will think that there is no such thing as a "stereotypical black person," or do these comments more tear people down, meaning someone will think "well, maybe I don't act black enough/act too white" and therefore should change.
This isn't the first time this has happened to me, and I'm sure it won't be the last. I've been called white and that I think I'm "too good for anyone" for going to college!

Do we, as blacks, take things too far when trying to generalize our culture/people?
