Me: Hey don’t walk on the floor. It’s mopped and very slippery.

Grandboy: Look I can walk on the floor (hops) and I can dance on the floor, Gwumpa (spins)

Me: O now look, you can fall on the floor, too. Cool trick.

Grandboy (picking himself up): That’s NOT FUNNY Gwumpa

Me: Then why am I laughing?
