I have some students that never touch their instrument except during the lesson. I talk to the parents, who are aware of the poor practice habits, but say that the lesson with me is the highlight of their week.

I have adult students that end up talking about their divorce, job, or other problems. They feel it is worth the fee and time to sit and spend twenty minutes of their thirty minute lesson time talking about life.

Yes, I agree. The music lesson can also be a therapy session.
