He is planning a big musical performance by his students, and they have been rehearsing their pieces. At the practice session, I was struck by the mix of people. They were fairly evenly divided between children and adults, which makes it interesting. I think A gets a kick out these situations.
We have a bit of a time conflict on the day of the performance, but will try our best to make it work out, because A is really looking forward to the show.
Until then, thanks for reading, and thanks to Peter Mazurek for the pic.
