On the bus, my son was humming the Choral from Beethoven's 9th symphony. This guy with piercings and whatever that get-up young guys are wearing nowadays says, "Hey, that's a nice song. What is it?" My son answered, "9th Symphony by Beethoven." The young man asked, "Beethoven, what's that?" My son said, "A big dog." A girl who was with the guy said, "Yeah, I saw that. It's a movie. Before our time." The guy said, "A film score, ok." Out of their line of vision, my son looked at me and rolled his eyes. I had to bite my lip to stop myself from laughing.
