Calculus lesson today. I'm really starting to learn about the derivatives. It makes me feel so much better. All thanks to you.

Well, calculus is pretty hard to get, but once you get rolling with it, you'll start to catch it.

Well, I really appreciate it.

Great.

Could I spare a few hours to talk to you about something? It's something that's just been going across my mind lately, and I think you'd understand.
