In the Atlanta airport, now: I’m sitting in my gate, waiting for my plane to board, and the teenage girl at the end of the row of seats is not only listening to her CD player at a volume that makes the music audible to half of the gate’s occupants, but is also loudly (and badly) singing along as if it’s the most normal thing in the world.

Odd behavior, that.

(Update: as the gate area has become more crowded, she has chosen to double her volume. Odder behavior, that.)
