I can picture him behind the lens, noticing the small specks of dirt on the glass and rubbing it in, slowly making it worse with his thumb. Trying to help but making it worse. But that's all he knows.
We need to remember we don't know everything, and as the sun dries up our spirits, drink a glass of water. Feel it enter your throat and dance through your body.
I can picture him taking the photograph anyway. He may have seen it differently, but the picture came out spotless. Eyes that have been nestled in the belief that a smudge is a stain. A stain is something bad, you must immediately get rid of it. But I think you should just go with it.
