My boy

Mimi always asks Adler who's boy he is. Usually he answers, "Mimi's boy!"  However, depending on his level on silliness, he will say, "Mommy's boy!" or "Papa's boy!" to make Mimi "mad."  Today she asked him, and he turned to me and said, "Mommy, you're MY boy!" so I keep telling him I won't be his boy anymore if he doesn't behave.
