Edilia, my suggested corrections and changes are shown below.
On a very cold morning, about eight o’clock when I was going to work I was passing through a small tunnel when I saw a man wrapped in his coat at the end of the tunnel. He may not have been old, but he looked like he had been badly treated by life and time. He was silent, with a hard, stony, and sad face that couldn’t leave nobody that passed through that path untouched / affected by his situation. He had in front of him a bowl with few coins inside. He looked at me and I could see that he was smiling wanly. His eyes were full of loneliness and sadness. I kept trying to tell myself, “Don’t pity him. He doesn’t want that, he doesn’t need that, and he will know it at once if I do. He is not a victim, he is a person / one of the people”!
