I don't think I can go back to teaching. At a ski retreat (I don't ski, but I had fun staying in the warm cabin), I was doing work on my laptop and enjoying myself. As I was about to leave, I realized I had forgotten my computer. I went back in, saying, "Almost forgot my computer," and a friend said, "If you forget it, you'll have to go back to teaching!"
That was enough to strike fear into my heart. Everyone else thought it was funny, but I didn't so much.
