Me: Will you stay a little boy forever?
Him: No. I'm growing.
Me: Can you just stop growing for a little while?
Him: NO! You can't put anything on top of me!!!!
Me: I won't put anything on top of you. Isn't it fun being a kid?
Me: Do you want to be a grown-up?
Him: Because....... I can have big knees. Daddy has big knees, Mommy has big knees....(sadly and with a little bit of a whine) I have little knees.
Me: through muffled laughter Oh, I see. Grown-ups have big knees.
