The following notice is hanging on the television in the family room right now. When my children come home from the various places they’ve spent Saturday afternoon, they will read (or have read to them, in Little Brother’s case):
If you are old enough to carry food and drink out of the kitchen,
Then you are old enough to return your cans, bottles, cups, dishes, bowls, and trash to the kitchen when you are done.
See to it. The Great Oz has spoken.
