The Last One

I brought doughnuts to the office the other day. In record time, they were almost gone--all but the last one. A co-worker saw it and hesitated to take it because, "It's the last one." I begged her to take it, and she did take it, but only after cutting it in half, leaving half a doughnut, which then was the last one. I had to leave, so never did find out if the next doughnut eater cut that last one in half, and the next person--half again--then again and again, until they were cutting the last crumb in half. After all, it would have been the last one.
