The kid, folding her socks: oh, no.
mr. delagar: what?
The kid: my socks have come out an uneven number.
Me: that's odd.
(Sorry. Can't help it. It's the only math joke I've ever made. And the kid loved it. She's good at math, not like her parents. She gave me this long suspicious look, and then rolled around on the bed giggling. "That's odd!" she kept saying. "That's odd!")
