The Bright Side

Dee (settling in on a branch next to her): Fifteen's a good number though.
Emily: What's good about it?
Dee: I don't know. It's just nice. Three times five.
Emily: So? It's not a prime, then.
Dee: I've never been that big on primes, actually. I like odd numbers that are divisible by other odd numbers.
Emily: ... Uh... huh.
Dee: Do you have a favourite number?
Emily: No. Um... maybe 13? 666?
Dee: You walking cliche.
(Emily shrugs, smiling.)
Dee: So anyway... um, people have parties on their birthday, right?
Emily: Yeah, if they have people they want to invite.
