On Christamas Eve - the night after Christams Day
children all over Britain put a stocking in the end of
their beds before they go to asleep.Their Parents usually
tell him that Father Christamas will come during the night.
Of course,Father Christamas isn't true.In Jim and Kate's
house,"Father Christamas" is really Mr Green.Often
Mr Green waits for until the children are asleep.Then
he quiet goes into theirbedrooms,and fills their stockings
with small presents.When they are yong,Mr Green
sometimes dressed in.But now he doesn't do that.
