My son makes things out of paper. He once made a moderately convincing machine gun, and he’s recently made a cube and a pair of scissors that actually scissored like a pair of scissors. Perhaps his greatest triumph to date has been this cello, which he modeled loosely on the cello his older sister now plays in middle school orchestra.

The little holes on the front, which sort of look like headless body builders because he misjudged the cut to make, are on a real cello called F holes, but when I was first acquainting myself with the instrument to help my daughter get started, I learned that the concave curves on the side are called the C bouts, had read that there were F holes, and managed to think briefly that the F holes were called the A holes, so that now occasionally I’ll do this schtick in which I name the other lettered bits of cello anatomy and express surprise that I never can find the A hole. I’m still waiting for my Father of the Year award.
