I've got a book about festivals of the world. It's interesting. And I know something more about Christmas. Christmas is a special festival in many western countries. Before Christmas, people have got lots of things to do. They send cards to their family and friends, and put Christmas trees in their homes. They put presents under the trees. On Christmas Eve, they open their presents and say" Merry Christmas" to each other. They sing and dance, and have a big dinner together.
