Christmas is a time for tradition, and every family has its own. Some go caroling; others sip eggnog. Most curl up in front of the TV to watch a holiday classic. But there, traditions vary too: Some like the holiday movies that make them laugh (National Lampoon’s Christmas Vacation, A Christmas Story), others prefer the ones that pull the heartstrings (Miracle on 34th Street, It’s a Wonderful Life). Which side of the chimney do you fall on?
