War has always changed men physically and mentally. They go away as healthy physically fit young men; when they come back, if they do they are not the same young man who went away. They may have suffered disabling physical injury in addition to a mental injury that may or may not manifest itself physically, but typically it is there. In World War I they called it shell-shocked, today we call it PTSD.
This is a short story by Edna Ferber of a healthy, husky, and slightly arrogant in a nice way young man, and the beautiful girl awaiting his return home. Lee Ann Howlett performs this short gem masterfully.>
