We drove by a field full of busy youth athletic leagues.
Caroline: Ooooh, what are they playing?
Mama: That's football. Flag football.
Caroline: Football, with flags??!! I think I'd like to play that!
Mama: Well, I think you have to be 5 to play. But if you're still interested in a couple years, sure, you can play. It's mostly boys, but there are some girls, too!
Caroline: That sounds like fun. And I can play tennis too.
Mama: We'd need to get you into pee wee tennis at the community center before you could play in any sort of league.
Caroline: I already know how to play tennis, Mama.
Mama: Really? I didn't know that. What are the rules?
Caroline: Oh sure! I definitely know how to play. You just, like, get one of those puppy balls. You know, the ones that are a little yellow and a little green and kind of fuzzy and have a white stripe? You get a dog ball like that, and, well, you just hit it. With one of those netty bats. I'm a pro, actually.
