It was my son's last day in middle school today, so we gathered in a very hot and overcrowded gym to give his class a good send-off.

The school choir sang a song for us. With the inadequate air-conditioner straining away in the background, the general shuffling and hubbub from the audience in a large room with terrrible acoustics, they had a hard time standing out.

But they tried their best. It was very sweet. And they got a very loud ovation.
