Christmas is a festival for family members to get together for reunion and people who live away to get back home. The roads and railways are full of people traveling long distances in order to spend Christmas at home. And above all, it's the children's festival.
The children count the weeks, then the days to Christmas. They are wondering what they are going to have; they keep trying to find something out from their mother, but the only thing the mother will tell them is stories about Father Christmas who brings presents to good children.
Christmas Eve comes at last. When the children go to bed, they hang up their stockings, and on Christmas morning they wake up to find them full of presents. Of course it's really their parents who fill the stocking, but even the older children often pretend not to know this.
Everybody likes to be happy at Christmas time. The theater puts on special shows for children. The circus is another thing that parents may take their children to see. Here, the audience sit in a circle and the performance takes place in the center. The main attraction is the peforming animals. Elephants, lions and tigers are trained to do astonishing tricks. Every circus has clowns who make people laugh.
