Supper time conversation

Elizabeth is making orange juice and wants to choose one of the kids to give the lid to so they can lick the juice off.

She says, "Tell me a number between 4 and 6." Jon shows 10 fingers. Phoebe says, "3!"

"Okay, what's 10 plus 10?" Jon shows 5 fingers. Phoebe says, "4!" "No." "3!" "No." "2!" "No."

"Let's see.... what's 100 plus 100?" Jon says, "10." Phoebe says, "Milk!"

She finally lets them each take a lick of the lid.
