Mom, why do people run marathons?
MICHELLE
I don't know, it's good exercise, and some people like to run.
CAL
But they have to run so fast and so far.
MICHELLE
Yeah, that's true. But, you know, some people enjoy that kind of thing.
CAL
Yeah. Crazy people.
(Edited to add: I was going through and labeling some old blog entries and found this conversation I had with Cal from around this time last year. Hee.)
