C: Charlie is a sweetie bird. The birdie. Sweetie pie bird.

L: Yes, Charlie is a sweetie pie bird.

C: Charlie boy. Charlie sweetie boy.

L: Yes, Charlie is a sweetie boy.

C: Sweetie girl?

L: Lucy is a sweetie girl.

C: Charlie sweetie girl?

L: Nooooooo, Charlie is a boy, a sweetie boy.

C: Nooooooo, Charlie boy. Hahahahahaha.
