Last night the Professor and I attended a private event at a museum. (It was put on by a company he owns a little stock in -- just 100 shares or so -- but they didn't restrict attendance to the wealthy ones.) It was actually pretty cool: we saw an Imax movie, had free drinks and food, and got to tour a new exhibit. We had to exit through the gift shop, and of course I stopped once or twice to look at something. That's where I heard this conversation:

HE (barely containing his anger): I've been waiting for you outside. I'm very upset. You didn't tell me you were going to shop.
SHE (very defensively): I'm not shopping, I'm just looking!
