One of the families in our HS group is offering a nature hike/ class in a few weeks and we signed up for that. One (or all) of us will accompany her. I have looked for some half day things and I found some tennis lessons she may like. Most of the clases at the Science Museum and so forth are full day for a week or more. I think it is hard for her to be on that kind of schedule. I like it when she finds something she enjoys for a few hours, gives us a change of pace.
