The story ended with the police coming and finding the person still there cleaning up fingerprints. The cleaning included the fruit at the bottom of the bowl. Fruit that had never been touched. The character was simply mad.
I think of that phrase whenever I see something completely mad. Particularly when I see behavior which is inexplicable. I've had a few "fruit at the bottom of the bowl" moments while on the High Council. I try not to have them while at home.
It just isn't necessary (or possible) to micro-manage your children's lives. Nor is it wise to try to micro-manage millions of other people's lives. Whether as a parent, as a government leader, business leader, or as a church leader, Joseph Smith's advice is still timely. He said the way he managed the church was to "teach them correct principles and let them govern themselves." I'd like to see a return to that. In all parts of daily life.
