This document is a photography.
The scene takes place in a hospital because we see a young man in bed with oxygen devices behind him.
We see an old man who seems to visit a young man in a hospital room. They are probably relatives.
The old man may pays a visit to his grandson. The young man must have broken his leg or he could have fallen from a tree. But it can't be a fight because there are not any bruises on his face
Explications : bruises : bleus, hématomes
