For some strange reason, my daughter rarely flushes the toilet. Fear of loss, perhaps? Regardless, it led to this exchange:
Me: Oh, look. Poop in the toilet. How lovely.
Daisy: Whoops. Sorry.
Me: Ok, from now on, everytime you forget to flush, I'm chopping off one of your arms.
Daisy: No way! I definitely wouldn't be able to flush then!
Me: Sure you could. You could flush with your feet, your tongue, or even your butt.
Daisy: Are you really going to chop off my arms?
Daisy: What if I hit you?
Me: No, not then either.
Daisy: What if I destroy the house?
Me: Baby, you get to keep your arms no matter what. I'll find other ways to punish you, but they won't include chopping off your arms.
Daisy: What if I destroy the house, and outer space, and the whole universe?
Me: Look, how about we just agree that you won't do those things?
Daisy: (heartfelt laughter) Oh, daddy. I'm already planning to do them tomorrow.
Be afraid, people.
