      On Christmas Eve─the night before Christmas Day─children all over Britain put a stocking at the end of

their beds before they go to sleep. Their parents usually tell them that Father Christmas will come during the

night.

      Father Christmas is very kind and hearted. He gets to the top of each house and climbs down the chimney

into the fireplace. He fills each of the stockings with Christmas presents. 

      Of course, Father Christmas isn't real. In Jim and Kate's house, "Father Christmas" is really Mr Green. Mr

Green doesn't climb down the chimney. He waits until the children are asleep. Then he quietly goes into their

bedrooms and fills their stockings with small presents. When they were very young, Mr Green sometimes

wore a red coat. But he doesn't do that now. The children are no longer young, and they know who "Father

Christmas" really is. But they still put their stockings at the end of their beds.
