You know, I’ve never actually had this scenario happen to me. Usually, the response to an unnatural hair color is somewhere along the lines of “I love it,” or “how are you going to get a job?” Fortunately, Andersen Library doesn’t give a shit what color my hair is.
I’ve gotten both the “you look so much nicer with your natural hair color” and “with your long hair”. On one of these occasions, it was while I was wearing a wig. The temptation to whip it off and be all “WELL I DISAGREE” was alarmingly high.
