A Christmas stocking is an empty sock or sock-shaped bag that is hung on Christmas Eve so that Santa Claus (or Father Christmas) can fill it with small toys, candy, fruit, coins or other small gifts when he arrives. These small items are often referred to as stocking stuffers or stocking fillers. In some Christmas stories, the contents of the Christmas stocking are the only toys the child receives at Christmas from Santa Claus; in other stories (and in tradition), some presents are also wrapped up in wrapping paper and placed under the Christmas tree. Tradition in Western culture threatens that a child who behaves badly during the year will receive only a piece or pile of coal. However, coal is rarely if ever left in a stocking, as it is considered cruel. Some people even put their Christmas stocking by their bedposts so Santa Claus can fill it by the bed while they sleep.
