In some countries, the most common unlucky number is thirteen. People don’t like to live in a house that is number 13. People don’t like to have parties with thirteen people. People don’t like to do important things on the thirteenth of the month. Also, when you add the Japanese unlucky numbers together---nine and four ---they make thirteen.

There aren’t many business meetings on the thirteenth of the month especially when the thirteenth is on a Friday. Friday is always unlucky. Adam and Eve left the Garden of Eden (伊甸园) on a Friday. Jesus Christ died on a Friday. There were thirteen people at his last supper. In Europe, they kill criminals(罪犯) on Fridays.

For some people, unlucky numbers do the opposite things. My elder brother was born on the thirteenth. He passed his exams on the thirteenth. He married on the thirteenth. He became a pilot on the thirteenth. It was always a lucky number for him.
