Tough Reference Question

I was walking by the circulation desk when I overhead a co-worker say this into the circ phone, "Um, find shelter?"

I turned to a nearby student assistant. "Are we under a tornado watch? What's going on?"

My co-worker heard me, sort of sputtered, and waved at me to go away. I went to my computer to check noaa.org. There was no tornado watch.

Once my co-worker was off the phone, I asked him about the phone call.

ME: What's going on? Are we in imminent danger?

CW: No, a resident advisor wanted to know what to do if it began raining during the first-year's tour of the libraries. I couldn't think of anything not snarky to say. I almost said, 'Ever heard of an umbrella?'

ME: So you told him to find shelter?

CW: Well, how else was I supposed to answer the question? What does he do when it's raining and he has to go to class?

ME: Skip.

CW: Obviously.
