I'm speaking of spilled milk, of course.
I came home a few nights ago to a pile of wet kitchen towels on the floor of the laundry room. (Incidentally, this is exactly where I ask the children to place things that need washing, as I find their sorting skills somewhat lacking in precision.) I didn't think much of this, and carried on with serving dinner and helping with homework.
In the context of a completely unrelated conversation, it came out that Bella had "helped" earlier that evening by bringing in a gallon of milk from the garage, and that she had accidentally dropped it by the hall closet. Naturally, the plastic split and an entire gallon of milk spread itself across the tile.
As I questioned the children about this, completely stunned that there was virtually no evidence of this having happened (other than the wet towels), I learned that Sam, hearing the spill from upstairs, dashed down and set to work cleaning it up without hesitation. No grown up asked him to do it. He had nothing to do with the mess. He just fixed it, and did a great job doing so. If I hadn't seen the towels, I wouldn't have ever known it had happened. That is a real first for me.
Sam definitely earned "kid of the week" in this family. May this helpful trend be contagious and oft repeated!
