My professor has an affectation. He carries around an eight-foot pointer, which he waves with a flourish and has taken to resting on his groin while answering questions.

So help me, I’m not sure what to think.

And just when I’ve begun to think that it’s just an innocent, ill-conceived habit, he strokes it.

Gently.

Friday’s forecast: Lots of professors take roll. But one will be really glad to see you.
