Jason writes about Battle of the Bands and how he and Goaty (the wife) studies the kids.

Goaty had a good time identifying cliques and social heirarchies in the
various fast-moving packs. I had a good time watching the performers
pull out moves they had obviously perfected in front of basement
mirrors – guitars were flying, fists were pumping, sticks were
twirling.

Go read the whole thing. And, while you’re at it, consider reading the man’s feed. He has a grip on his prose that I envy.
