Peanut: Hey Mom! I have something very surprising and exciting to tell you.
Me: Ooh, what?
Peanut: T's cat had three kittens.
Me: Oh, wow. They didn't know the cat was going to have kittens?
Peanut: Nope. They were just sitting on the couch one night watching TV and their cat started having kittens.
Me: Oh my. That really is a surprise then, isn't it?
Peanut: Yep. But, I just know that my guinea pig will never have babies.
Me: No. Your guinea pig will never have babies.
Peanut: But she might.
Me: Um, do we have a boy guinea pig?
Me: Then how would your guinea pig have babies?
Peanut: I dunno. She just might.
Me: Peanut, didn't we talk about where babies come from?
Peanut: I dunno.
Me: We did. Do you remember, it takes a boy and a girl together to make babies? We only have a girl guinea pig. No boy. No babies.
Peanut: Oh yeah. Wait, then how did T's cat have kittens?
Me: T's cat met a boy cat outside.
Me: I have no idea.
Peanut: I bet it was Slinky.
