The most annoying kid ever

BB and I went to the supermarket yesterday. Unlike the little health food coop, the aisles in the supermarket are big enough to skip, run, and jump around in. Which is what BB does. He fell once and I must have said slow down at least 10 times. But mostly it's harmless. He did use the opportunity of a passing cart to scoot by me, barely missing the old woman pushing the cart. That garnered a sterner warning from me. I was pleased, though, when he became the most annoying kid ever. We got stuck behind a costumer and her daughter having some problem about a price or scanning their credit card. I became more and more impatient as a supervisor was called over. I was delighted, then, when BB took one of the usual objects in his hand and began banging it repeatedly on the metal portion of the conveyor belt. Bang, bang, bang, while the costumer ahead kept looking over with increasing annoyance. I could have stopped him immediately. But I let him keep doing it for a full minute or so. Bang, bang, bang. It was what I wanted to be doing. Finally, I pulled him away and he quit without a peep. Vengeance was mine! It occurs to me that all parents must use their kids as passive aggressive mechanisms from time to time.
