In some foreign countries, some people don't like the number 13. They don't think 13 is a lucky number, for example, they don't like to live on the thirteenth floor.
One day, my friend Jack asked some friends to dinner. When all of his friends arrived, he asked them to sit at the table. He began to count the people in his mind while they were having the delicious food. Soon, he cried out, "Oh, there are thirteen people here!"
Everyone's face turned white except Mr. Brown. He said slowly with a smile on his face, "Don't worry, my friends. We have fourteen people here. My wife Mrs Brown will have a baby in a few weeks. She is in the family now. "
All of them became happy again, "Congratulations!" they said. They all had a good time that evening.
