Dr. Gupta: You do not have to keep your hand raised, just raise it briefly and I’ll call on you.
Me: I usually do, but sometimes you miss.
Dr. Gupta: No I don’t, that’s why I don’t ask you to keep your hand-raised.
Me: But you’ve missed me a few times.
Dr. Gupta: I don’t miss anyone.
That’s not circular, at all.
