As she rounded a corner one of her favourite songs came on the radio, and sunlight filtered through the trees the way it does with lace curtains, reminding her of her grandmother, and tears began to slide down her cheeks. Not for her grandmother, who was then still very much among the living, but because she felt an enveloping happiness to be alive, a joy made stronger by the certainty that someday it would all come to an end. It overwhelmed her, made her pull the car to the side of the road. Afterwards she felt a little foolish, and never spoke to anyone about it. Now, however, she knows she wasn’t being foolish. She realizes that for no particular reason she stumbled into the core of what it is to be human. It’s a rare gift to understand that your life is wondrous, and that it won’t last forever.
