There they are, lined up like sentinels behind the scaffolding. I am always excited when the Christmas trees come to town, even if I never buy or own one, because they transform barren concrete sidewalks into magical tiny forests. Every time I walk by the fragrant firs, pines and spruces, I am transported from grey New York to my own private Narnia. Arriving around Thanksgiving and lasting until Christmas Eve, the seasonal trees elevate mundane places and turn routine chores into an adventure. You never know who might run out for a tube of toothpaste to a 24-hour drugstore at 2 a.m. and come home instead with a ten-foot spruce. And I can’t help wondering, are these truly just trees, or maybe—for those with special vision—a line of deep green uniformed soldiers guarding a dark red castle? Each time I walk by, I breathe deeply and stand a little straighter. You never know who might be watching.
