Glad to hear your son coming home. Wish they all were. Asked my mother once if she had noticed a differnce in my Father or I when we returned home from war. Father in Pacific in WWII and I was in Vietnam. She did not hesitate in saying yes. Father had trouble sleeping, any noise would wake him. I had same problem. Also, the sound of a bullet whizzing nearby will still cause me to instinctively react without thinking. First happened two years after leaving Vietnam, when a bullet passed well over my head when I was walking across an parking lot of a rural store. I dove face first on the pavement without thinking, or actually knowing why I had done it. While I laid on pavement, another round whizzed well over my head. Seems someone was shooting at billboard sized sign of the store from a great distance away. You could not hear the sound of the gun, just the bullet. 33 years later, another bullet will whizz past me and again I will drop to the ground without thinking about it. So, there will be some things about war a person will never forget. There will be things you will forget in time, and other things you will learn to cope with. Like my father and I, your son will be OK. It may just take time. Be caring, patient and understanding. Give him his space, but be ready to listen to him if he wants to talk about it.
