Apples In My Future?

Reconnected with RW today after not having spoken with him in a long time. He was very gracious, and we both spoke about the ways in which parenting can change your sense of time and what is achievable. He offered to talk with me about working at his school, and we also want to get the families together at some point. When I mentioned that several friends have asked me if I'd consider teaching, he asked what grade levels I'd be interested in, and I said, "Secondary, I guess," because that's the age level I've had the most experience with. What I should have said, I think, was, "I have no idea! How does one make that determination other than through trial and -- hopefully not too much -- error?"
