Conversation Excerpt Between My Sister And I

D: I've noticed Wendy isn't getting any bigger. But she's a pony...

J: Right. But she's 23. She's not getting any bigger, except maybe just wider.

D: So ponies aren't just young horses, but also little horses?

J: Right.

D: So she's a horse midget?

J: Right, but she probably wouldn't appreciate you calling her that.
