Just a quick FYI, Jillian and I are going to meet a prospective piano teacher Saturday morning. She is a Suzuki teacher. We chose Saturday because she'll be giving a lesson to a 7 year old girl then, and she invited us to sit in.
If I were her (and/or if I were the student), this would freak me out a little... perfect strangers evaluating the proceedings, to decide if they want to plunk down a bunch of money for lessons. But this is, apparently, not uncommon, so we'll go with it.
