Yesterday: tennis, long bike ride, park (ping-pong, scooting, climbing trees, paddling pool). Got him to sleep (read into submission) at 9.30 and he woke me up at 6.45.
He's storing up his sleep requirements for tomorrow, isn't he? He'll be impossible to get out of work in time for holiday club... Off to the bloody park for more tennis and it's not even 8.30 yet.
All reasonable suggestions considered - drugs, drink (for me), blunt but non-permanently damaging implements to the cranium, selling him to the local chimney sweep, duck tape.
