successful exit

Maybe it was singing "goodbye museum", maybe it was having the excellent example of his older sister to follow, or maybe it was just being tired and hungry and having the promise of snacks and rest in the car, but Q left the Discovery Museum today calmly and without any struggle or reluctance at all.

Am now picturing a program in which museums etc keep a well-trained older child on hand as a sort of Judas goat to lead resistant small ones out of the building...
