Christmas is the most important festival in the western world. It falls on December 25th. When my mother and I stayed in America, we were invited by one of my mother's friends to have Christmas with an American family. We bought some presents for our American friends on our way to their house. They had prepared different kinds of gifts for their family and guests when we got to their house, such as Christmas candles, cakes, cards, little toys, biscuits and so on. A Christmas tree was placed in the comer of the brilliant hall. How beautiful it was! We were impressed by these. We had a big meal. After dinner, they told us some interesting stories about Christmas. We learned that Christmas had something to do with God. We went to bed at midnight. Though we knew the Santa Claus was not true, we were still waiting for the Santa Claus with white beard to bring us presents.And we received many beautiful presents the next morning. This Christmas was really unforgettable. Not only did I have a good time, but also I knew something about foreign culture.
