You're walking down a lamplit street on a crisp winter's evening. A scarf is snug around your neck, frost nipping at your fingertips and nose. Is that the smell of warm fireplaces and snow? No, it's these Holiday Plagues, who come strolling around the corner, hand in hand, singing carols and comparing hot chocolate recipes.  You join them. You make a snowman together. You sing more carols. It's a good evening.
