It was four minutes past midnight on a warm evening in early May. A few drops of rain were starting to fall as I returned home to my apartment.
I was very much looking forward to the last piece of chocolate angel food cake that was waiting for me in my refrigerator. I hurried to the kitchen.
I was horrified to discover only an empty plate, retaining but a few tiny crumbs of the cake's former glory.
Nothing else in the apartment had been touched, and my anger grew as I pondered the mystery of the vanishing cake. I thought, Who would do this? Who would break into my home just to eat my last slice of cake?
Then I noticed a pink envelope on the table. I tore it open. It contained a small pink card, bearing a neatly printed word: "Thanks."
