Have you ever tried to put milk in the cupboard or a box of cereal in the fridge?
I was warming up a tortilla shell in the microwave and while I was waiting I watched [10 seconds of] something on TV. When it beeped, I was still listening to the TV and I went to open the freezer instead of the microwave.
I guess that's more of being preoccupied.
But have you ever done anything like that? What did you do?
