If you are born in summer, you could be sunny person. If you are born in winter, you could be less sunny. That is to say, the season of birth affects our personality.

The result comes from a study of mice. In the study, some mice were given 16 hours if light and eight hours of darkness every day. This is like the long days and short nights of summer. Other mice had only eight hours of lights. This like the short days and long nights of winter. After some time, scientists placed the mice into darkness, and watched what they would do.

"Those summer mice eat, play and sleep as usual, but those winter mice have difficulty in dealing with the change. " said a scientist.

This is just like humans. Those winter babies will spend more time dealing with a change in seasons. This will slowly affect their mood and their outlook towards life. Well, you can watch your classmates and find whether this result is true.

Long, long ago there lived a man in a small town. His name was Nicholas. He was a bishop. He usually wore a long red robe with a red hat.

One day, Nicholas heard a sad story of poor old man and his three daughters. That night, Nicholas climbed up to the rooftop of their house, and dropped three bags of gold down the chimney. Each bag fell into one of the stockings by the fireplace.

The next morning, the girls were surprised to find gold coins in their stockings. "We have got a magic gift!"
