A: Mom, here, hold my hand. I'll keep you warm.
(a block later)
M: Can't you put your hands in YOUR pockets and I'll put mine in MY pockets? I think we'll be warmer.
A: I can't. I don't have any pockets.
M: Yes, you do, right there on your coat.
A: Not EMPTY pockets.
M: Why? What do you have in your pockets?
A: Glasses and rocks.
