I imagine I'll be teaching again sometime soon, because I really enjoy it, but right now I need my energy to focus on other things. I've been kind of depressed recently and don't have much energy to spare, so I think it's for the best. I was actually pretty terrified about telling the school that I needed a semester off, but they were very cool about it.
(Of course, I haven't yet asked the ITP folks for a recommendation, but hopefully they'll still be happy to give me one.)
