Dear LFTP: the restaurant butt-crease letter

• Would it have been appropriate to quietly tell a mother that her young son's buttocks were exposed at a restaurant?

A listener asks what to do when seated across from a family whose 12-to-14-year-old son's buttocks are exposed through the whole meal at an expensive restaurant - should he have quietly told the mother? Hosts riff on 'bleavage,' plumber's pants, and moving chairs; Secular's advice is read: move your chair so the view isn't head-on.
