On the weekend I went over to friends for dinner.
We were discussing the body shape of someone, and it came up that they had "no legs" and "no butt". To the adults in the room - it meant skinny legs and a flat rear end.
But to a six-year-old...
Five minutes after we've finished the conversation he pipes up... "But how does she walk if she has no legs and no butt?"... much laughter ensued from all the adults in the room as we explained what we really meant.
Kids sure say the darndest things.
