Guillermo was a homeless man who lived in our alley when I was about 9. He never caused any trouble and kept to himself.
My mother and a couple neighbors would cook a little extra food to feed Guillermo, and would help to keep him sober. He soon started to open up and let us know about where he came from, what he did, and why he was where he was.
One day he said he wanted to go back to his family and left. Came back a year later clean, sober, and with his daughter. He came back to thank my mother and neighbors for taking care of him and not letting him get lost in alcoholism.
