Returning from a trip to visit my grandmother in California, I was
stopped by a state trooper in Kansas for exceeding the speed limit.
Grateful to have received a warning instead of a ticket, I gave him a
small bag of my grandmother's delicious chocolate-chip cookies and
proceeded on my way.
Later, I was stopped by another trooper. "What have I done?" I asked.
"Nothing," the trooper said, smiling. "I heard you were passing out
great chocolate-chip cookies."
