I'm also feeling a bit sad because I turned down an offer of regular work. Basically somebody asked me to teach a group in their house. But it would be a big, long term commitment and bearing in mind it'd be an hour travel each way (it's the other side of town, so two buses) and obviously my health being the way it is, I just can't.
I may get some pupils (who would come here) out of it, but even if I don't, I think I made the right choice - I got a bit of an odd vibe about the whole thing (other parents agree and have gone elsewhere), and I'm not sure I'd feel comfortable being basically employed to teach (by somebody who doesn't know the subject), rather than being freelance. Shame though.
