Lovely Lavender Hand Soap Tells All

Me: Oliver, time for dinner! Please go wash your hands.
Oliver: Ok Momma!

a few moments later...

Oliver: Ok Momma. All washed! Smell!

He proudly presents me one hand to sniff. We have lovely lavender hand soap that I can smell on freshly-washed little-boy hands.

Me: Oliver, why is your other hand in your pocket?

blank stare...

Me: Oliver?
Oliver: Momma! I only use ONE hand to eat!
