I've thought back on this more than once. Last year, while walking on the Vegas strip, one of the guys standing on the sidewalk soliciting donations said something like "hello ma'am" to me. I was wearing men's clothes, and, to the best of my knowledge, exhibiting no external female characteristics. I shot him an icy stare, and he said "sorry -- I meant sir."
Has this ever happened to anyone else? Do you think it was just an odd coincidence?
