This has happened to me a couple times in years long past. There’s also the reverse, where someone you ONLY know from a goth club runs into you in everyday life, and it’s like “who the fuck are you and how do you know my name? OH, right, I’m used to seeing you in a long pink wig and a fishnet shirt with your nipples covered by electrical tape X marks.”

EDIT: Holy fucking shit, I fucking told you so.
