the slouching trombonist

We attended the middle school band/chorus holiday concert tonight, and I was interested -- but not entirely surprised -- to discover that my middle child has the worst posture in the entire 7th grade band.

Note the stylish white socks and black shoes combo, too.

I have no idea how he has any sort of lung capacity slouched over like that, let alone how he keeps the trombone slide from hitting the floor.

As an aside, I found this joke when I was checking the correct term for a trombone player:

Q: What do you call a guy who knows how to play the trombone, but doesn't?

A: A gentleman.
