It occurs to me that my mischief yesterday might have been too subtle to be appreciated properly. The human female has learned how to make “yummy steel cut oatmeal” overnight in the slow-cooker. It only works, however, if one remembers to turn the appliance on. She did. I turned it off after she went to bed. This morning she merely thought she had forgotten. She didn’t blame me, so while she was disappointed, I didn’t have the satisfaction of her knowing it was me thwarting her.
