Naughty or nice

Recently while shopping, I had to place Amy in "time-out" because she chose to pull several items off a shelf. After her time-out was completed, she told me, "Mommy, Amy can come out of time-out because Amy's going to not be naughty anymore." Not 30 seconds later, she repealed her decision: "Amy's going to be naughty now and touch the cars." Glad she warned me at least...
