Over the years, I've often ridiculed people for mistaking me for, in no particular order:
--a raucous partygirl
(most notably by one of the regular customers who always came into a bakery I used to work at; this stemmed from the time he asked me how my weekend was and I told him I couldn't remember; for some reason this made him assume I had spent the weekend in a drug and alcohol-fueled stupor instead of lazing around reading books, which is probably what I actually did).
