arm hair=fab, ignorant co-workers:not fab

so, i work with someone that continously makes comments that are offensive to everyone in the office, however they get away with it because everyone knows they are an idiot when it comes to thinking before they speak. this has recently come to a head with me when they pointed out my arm hair (a la natural, baby) and said i "needed to shave it." um, i don't need to do anything, and how dare you imply i should conform to your standard of beauty. this is especially annoying because they themselves are not fulfilling general norms of beauty (ie smokes, is overweight, wears ill fitting clothes). it took everything i had not to point out these things to her. we were in an elevator with the rest of our co-workers (yes, they are also rude enough to say something like this in front of a crowd) so i held my tongue except for my one comment of "i know this girl did not just say that to me." i am also annoyed because i think it's ridiculous to care one way or another whether anyone shaves anything, mind your damn business and keep your judgements out of my pits.
