Twice, my daughter has returned home from individual piano classes with a male teacher and gone straight to the bathroom, the first time washing her legs down with a jug of water, the second time straight in the shower. When asked about it she looks at me like, what's the big deal. She seems in all ways fine and is very motivated to learn the piano. I ask about the lessons, she says she enjoys them or she would ask to stop going. I ask what the teachers like she says what do you mean what's he like. So I am freaked out and am going to have a talk with her about other people and what it's ok and not okay for them to do. Any advice on how to approach this without freaking her out too, but helping her to feel she can confide in me if she needs to? The lessons take place at a large, busy music school with a good reputation.
