Write about people having hot chocolate. Are they children coming in from a snow-day? A romantic couple sitting by the fire on Christmas Eve? People wishing they had somebody to sit by the fire with? Practice dialogue—make them have a long conversation.
Imagine sitting by this windowsill. A vanilla candle burning and seasonal greens adorned in twinkling lights nearby. Outside, a cold and beautiful winter landscape. But you are here, inside, warm and safe.
