Ohhhhhh how'd I'd love to. But he's not my kid so I have no authority to do so. Best I can do is time out, stern voice and the hard scowl thing (evil eyes and eyebrow).
Good thing is, he's a good sleeper. By the end of reading two Sesame St. books he's sacked out. Probably just saving up energy for tomorrow. Odds are, 3 to 1 that he flushes half a roll of toilet paper down the tube and I'll have to plunge the toilet again since his last visit.
My kids, they are complete angels. They never do anything wrong and never act up. Once again they are complete angels (insert satire smilie here)
