Christmas is associated with warm family atmosphere and a house that is beautifully decorated. A Christmas tree placed in the representative part of a house is normally considered to be the most characteristic Christmas item. Obviously, it should be decorated with Christmas balls and colorful lights. Christmas mood is intensified by a traditional fireplace, at which we may warm up after a winter walk. The view of pleasing play of flames as well as a stylish stone or brick trim, which is decorated by conifer branches or characteristic colorful socks, is associated with Christmas American films, Christmas cards and illustrations from the books for the youngest ones. During the Christmas Eve the whole family may sit by the fireplace, sing carols together or drink hot chocolate. Children believe that Santa Claus with a bag full of presents enters houses through chimneys and for that reason they leave milk and cookies near the fireplace.
