Toothless

“Mom! Mom! I kicked out Tom’s loose tooth!” Jack announced, the leader of a thundering herd of boys racing up the stairs.

“You did what?”

“Remember how he accidentally knocked mine out with the doorknob that time? Well I accidentally kicked his out while we were playing.”

“And now I get to put it under my Pillow!” Tom crowed. “Thanks, Jack!”

They stand beaming their gapped toothed grins at one another for a beat, then someone suggests Tom go look at the blood in the mirror. They gallop away, and their dad and I are left bewildered, wondering what, if anything, we are supposed to do about Jack having kicked Tom in the mouth hard enough to dislodge his already loose tooth. If both parties are thrilled, has there been a crime?
