If he’s really serious he will start enumerating on his outstretched fingers, which is even more hilarious. And if he’s angry to boot, he’ll say we should call the police and report the infraction to them. He’s big these days on having the police come and put Sean in jail for teasing.
He also likes to fixate on the fact that Mommy won’t share cake, which is not quite fair, since Mommy not sharing cake means that after he has finished his own piece, I won’t let him partake of mine. I wouldn’t so much call that “not sharing” as I would “not spoiling” or “not being a pushover.”
