I have a couple adult students right now, and I very much enjoy working with them, not least because of conversations like these:
Me: We discovered a ridiculous amount of dust on the shelves above the bed.
V (in a French accent, on account of she's French): Oh, I think the dust can be pretty. When the sunlight hits it just so, you can pretend it's silver.
I like the way she thinks.
The next conversation was in the context of how chocolate is toxic to dogs and cats.
Me: When I was in college, I had a roommate who had a dog who ate an entire pan of brownies. He was sick for a day, but he was fine. I don't think I could even eat an entire pan of brownies.
K: Oh, I could. If I had to.
Me: If you had to...
K: You know, if someone came up and said, "You have to eat this pan of brownies or you'll never see your family again." Although that's probably not very likely to happen, is it?
If you don't eat the brownies, the terrorists will win.
