On Christmas Eve—the night before Christmas Day children are very happy. They put their stockings at the end of their beds before they go to bed. They want Father Christmas to give them some presents. Mr Green tells his children that Father Christmas is a very kind man. He comes on Christmas Eve. He lands on top of each house and comes down the chimney into the fireplace and brings them a lot of presents. Christmas Day always begins before breakfast. The children wake up very early. They can’t wait to open the presents in their stockings. Then they wake up their parents and call “Merry Christmas!” Do you know what Christmas means? Christmas Day is the birthday of Jesus Christ. When Christ was born, many people gave him presents. So today, people still do the same thing to each other.
