Brotherly Love

Conversation while playing Gameboy:

L: Camden, we're going to Grandma and Grandpa's tomorrow
C: I know
L: And we're bringing the dessert
C: I know
L: It's Oreo cake
C: I know
L:I'm gonna have the biggest piece
C: No, you're not
L: At least bigger than yours

Ah, brothers. Is there anything else like the rivalry they share?!
