Most holidays bring certain colors, sounds, smells, and traditions with them. They are different for every individual. Some of my favorite things for Thanksgiving and Christmas are:
Smells:
Cinnamon, cloves, pine trees, pumpkin, turkey, fresh home made rolls
Sounds:
Holiday music, laughter, bells, crunch of snow, crackling fire
Sights:
Holiday decorations, brightly colored leaves, family togetherness, brightly colored bows and ribbons, Christmas lights, the nativity scene, snowmen
