The bus ride was a blur of colors and passing faces. David barely noticed the jostling crowd or the screech of the brakes. He was lost in a world of his own thoughts, a smile stretched across his face. He felt like his feet weren’t even touching the ground.

He burst into the community center, his eyes immediately searching the walls. He was thrilled. There it was. His photographs, capturing the raw beauty of the city's hidden corners. He had spent hours wandering the streets, and it all felt so worth it now.

He watched people examine his work, pointing and gesturing. A woman laughed, and he felt a thrill of pride course through him. He had to clench his hands to prevent himself from jumping up and down.
