Celebrating Christmas became popular in the nineteenth century, after many German and Irish immigrants had come to America. Today, people might start saving for Christmas in September or even in August. However, the Christmas season really starts right after Thanksgiving. Street lights and store windows are decorated in the traditional Christmas colors of red and green. Snowmen, Santa Clauses, and Nativity scenes appear in many shop windows.
Young men enjoy mistletoe very much, because they can kiss any girl they find standing under it.
People send Christmas cards to their families, relatives, friends and business customers. Many people do Christmas shopping in December. They look for nice gifts for their family, relatives, and friends. It is said that stores make one quarter of all their sales during the Christmas season. Most shopping centers have huge crowds before Christmas.
