Christmas decorations are like smiles from complete strangers. Seriously, think about it. Among those who celebrate Christmas, people without hope or no sense of joy do not hang Christmas decorations. No matter what they're going through or what life is throwing at them - a wreath on the front grill of a truck, glowing colored lights hanging inside a dormitory apartment, garlands on almost every house in your neighborhood (even the ones that could use some work) - decorations are exclamations of happiness and hope. Each and every little light makes me smile.
