Child: I don't WANT to go outside. NO. I WANT to go outside. NO. Yes. I want, I don't want... (Child dissolves in tears because now he has 1) forgotten what it was he was talking about, and 2) can't remember if he wants or doesn't want it. Adults are trying not to laugh.)
Repeat for every conceivable notion during the day. (Lemonade, play with blocks, turn off/on TV, etc. Very entertaining, plus, uses up lots of time!
