Christmas Card Oops! Last Christmas, grandpa was feeling his age, and found that shopping for Christmas gifts had become too difficult. So he decided to send checks to everyone instead. In each card he wrote, "Buy your own present!" and mailed them early. He enjoyed the usual flurry of family festivities, and it was only after the holiday that he noticed that he had receiving very few cards in return. Puzzled over this, he went into his study, intending to write a couple of his relatives and ask what had happened. It was then, as he cleared off his cluttered desk that he got his answer. Under a stack of papers, he was horrified to find the gift checks which he had forgotten to enclose with the cards.
