Ballet.

I don't exactly enjoy picking up the girls from the bus stop and beelining across town as they change in the car (finishing once I've stopped) in order to be on time for their 4pm ballet class or the subsequent drive home back across town right at the pinnacle of rush hour traffic, but I do think they look so cute in their ballet outfits and they are enjoying it so far (2 classes), so I guess it's worth it.
