Last year, my youngest nephew walked on the white beaches under an overcast sky, and quietly stared into the distance. I do not know where he sees, but I understand something unique to him and only him, something that I will never see. I can only stand behind his back, intuitively understanding that he is thinking, yet having no idea what composes his thoughts. Similarly, I can stand at a distance from my eldest sister, photograph her onlooking, and only after the fact realize that her expression resembles a nostalgic sadness. But again, I will never see what she sees.
