So the other day my fourteen-year-old son was scooping out ice cream. It was frozen very solidly, and when he went to scoop some from the carton he used too much force and it went flying off the spoon and onto the floor.
Hate when that happens.
I pointed out to him that when you pick up the ice cream off the floor, you can run it under warm water in the sink and any yucky parts will flow down the drain, leaving clean ice cream.
He was extremely impressed with this information.
Passing on this kind of knowledge from one generation to the next is going to win me some kind of parenting award. I'm sure of it.
