A man worked in a post office. His job was to process all mail that had illegible addresses. One day a letter came to his desk, addressed in a shaky handwriting to God.
He thought, I better open this one and see what it's all about. So he opened it and it read, "Dear God, I am an 83 old widow living on a very small pension. Yesterday, someone stole my purse. It had a hundred dollars in it, which was all the money I had until my next pension check. Next Sunday is Easter, and I had invited two of my friends over for dinner. Without that money, I have nothing to buy food with. I have no family to turn to, and you are my only hope. Can you please help me?"
The postal worker was touched, and went around showing the letter to all the others. Each of them dug into their wallets and came up with a few dollars. By the time he made the rounds, he had collected 96 dollars, which they put into an envelope and sent it to her. The rest of the day, all the workers felt a warm glow thinking of the nice thing they had done.
Easter came and went, and a few days later came another letter from the old lady to God. All the workers gathered around while the letter was opened. It read, "Dear God, how can I ever thank you enough for what you did for me. Because of your generosity, I was able to fix a lovely dinner for my friends. We had a very nice day and I told my friends about writing to you. By the way, there was 4 dollars missing. It was no doubt those thieving bastards at the Post Office."
