Harmony

Everytime when I looked into this photograph, I thought I had captured a moment, where gloomness and calmness looked as though they are in harmony.

Here is a sticklike old man toiling up a trolley fully-loaded with paper carton, probably heavier than his own weight. But yet, his facial expression reveals a sense of calmness. It looked as though he didn't mind the gruelling task under the scorching hot sun. What was he thinking? Was he happy because of he collected so much paper carton and it's going fetch him more money than the usual?

Ironically, my sadness was comforted by his calmness of his face, as though he is comforting me. In retrospect, what right do I have to freeze the moment of an old man's life like this one?
