You know how people (librarians, mostly) always say, "Oh, no - there are no stupid questions" when they're trying to make someone feel better about whatever question they're asking?
Well, I'm going to break with tradition here and say that, yes, there are stupid questions. Lots of them, in fact, and they're frequently asked at my desk. For example...
Patron: "Do you have any um...German books? I don't know where to look. You know - like ones that are like, German-to-American?"
Me: "Well...sure. Okay, I'll show you." I guided her to the shelf containing the library's small collection of German-English dictionaries, deciding that I would just smile blandly and not venture into linguistics. I muffled a sigh on the walk back to my desk, telling myself that it would be most undignified if I were to run sobbing from the building.
