I was at a fantasy convention recently and there was a booth where they were painting faces and putting eyelashes on people for a small fee. I was walking by with a female friend and we started talking to the ladies at the booth. Then, one of them turned to me and said, with no irony or sarcasm "would you like some eyelashes put on?"

Here's the thing: I wasn't presenting as a woman. As a male I didn't look particularly feminine either. But it seems perfectly reasonable to her to ask me, not the woman I was with, if I would like eyelashes.

So my question is have you ever had someone just seem to "know," especially a stranger?
