The most common assumption that I ever can recall being made about me through most of my life is that i'm a violent person, but I just don't show it. Usually when I would question why i'd be told i'm either "too quiet", or it was because I wore nothing but dark colors, mostly black. "Stoner" was also a big assumption during my high school years when I grew my hair out. Even two of my teachers assumed I smoked pot before class, one of them sent me to the school nurse to get checked out one time.
