I visited my son’s first grade class last week and witnessed a kid put his backpack on the ground then whip out the telescoping handle and walk to the school bus as if he was catching the red-eye to JFK. This encroachment of grown-up behavior in an elementary school struck me as exceedingly strange. But then I checked out Lileks this morning, and there’s a picture of Gnat with her “Hello Kitty” travel backpack.
