My mom was a psych RN and when we were kids she worked at a V.A. hospital that was essentially a old folks home / mental hospital. Late 60's - early 70's.
She would take me and my sister with her sometimes when she would go in on her off days to catch up on paperwork. There were quite a few WWI vets. Some were just old men in a rest home but there were a few that we were told had shell shock. For that matter there were WWII, Korean War and Vietnam vets there that were in the same shape.
There was one old man who my sister and I loved. They called him Honey. WWI veteran who had probably 1/4 of his skull missing. Huge depression in his head.
Momma would give us a stick of Juicy Fruit gum and tell us to go give it to Honey and visit with him. He loved that gum. And he loved talking to us.
I still think about Honey to this day. I never asked what happened to him in the war. I imagine his life after the war was not great with such an injury.
He seemed happy in that hospital. I know all the nurses loved him.
