I think I was accidentally offensive and didn't mean to be. This guy came to our door (randomly, i may add) saying he wanted to buy a phone that we were selling. So I was like "sure let me get my brother for you, he does the selling" and closed the door on him. :| I wasn't thinking. I guess my brother did the same when he came up and then went downstairs to find the phone. I realized that a) no matter who he was I should have invited him inside and b) he happened to be black, and I was hoping that it didn't seem like "oh yes we're not going to let the black man in our house." I just remember how it feels when people acted weird and/or uncomfortable around me because I looked different (i.e., lesbian and/or gender non-conforming = pervert), and I wouldn't want to make anyone else feel that way. Hopefully he didn't think we were thinking along those lines. I wasn't uncomfortable because he was black, I just have no manners.
