Someone. Must. Pay.

Sunday evening before bedtime, Myles was playing in the living room. I thought I heard a particular bodily noise so I asked him, "Did you just pass gas?"
He nodded his head with some exaggeration and wore a proud, tight-lipped smile.
"Well? What do you say?" I asked, knowing that this usual prompt got an "Excuse me" out of him.
He raised his right hand, and held it there, waiting for me to complete the "High Five" with him.
