This excruciatingly personal thing happened at the Tenemenet Museum:

MUSEUM EDUCATOR: And, we're about to take a tour focused on the textile workers of the Lower East Side. Does anyone here have any experience with the textile business? Has anyone ever worked there?

(silence)

MUSEUM EDUCATOR: Um, does anyone have any questions about how the textile industry runs, today or in our past?

LARGE WOMAN: Yes, how come when you buy clothing that's a size, say, fourteen, with some companies a size fourteen is smaller than others?

MUSEUM EDUCATOR: I'm really not sure.

LARGE WOMAN: Well, they should try to figure that out.
