The waiting room was filled with the murmur of nervous conversations. I found myself focusing on the way the sunlight streamed through the window, illuminating dust motes dancing in the air. It brought back a vivid picture of the sun-drenched fields I used to run through as a child, the endless blue sky above. I remember the laughter, the feeling of freedom.

I saw my friend, David, across the room. He was looking at his hands, just like he did when he was thinking. I felt a yearning for a simpler time, when our biggest worry was who would be the first to reach the treehouse.

I caught his eye, and we shared a fleeting smile. It was a moment of unspoken understanding, a shared acknowledgment of a past that shaped us. It was a nice feeling.
