In the United States and other countries, this old Scottish song, "Auld Lang Syne" is played when a new year begins. The song is about remembering old friends. New Year's is a holiday for memories and for hopes. The past and the future come together at midnight. Not surprisingly, emotions are as much a part of New Year's Eve as noisemakers and fireworks. After all, a traditional way to welcome the New Year is to kiss the person you love.
