As you’re using e-mails, remember that sending and getting letters can sometimes bring about serious trouble.
When Jim left the snow-covered streets of London for a holiday in New York, his wife was on a business trip and was planning to meet him there the next day. When he reached his hotel in New York, he decided to send his wife a quick e-mail. But he couldn’t find the piece of paper on which he had written her e-mail address. He tried his best to remember where he had put it, but failed. Unluckily, he made a mistake and sent it to an old woman. Her husband had died a few years ago. When she saw the e-mail, she gave a terrible shout and fell on the floor. Her family rushed into the room and saw the message on the computer.
“Dearest wife, everything is ready for your arrival tomorrow.
Love, Jim.
P.S. it’s hot here.”
