My father-in-law was in the Marines for twenty years. He served in Vietnam. My brother-in-law was in the Marines for twenty years. He went to more different country's than I can remember. My niece was in the Army for four years. She met her husband in Iraq. They returned to the US, finished their commitment and stayed in the area where they were stationed and worked as civilians. They had a very happy life until one day her husband went home at lunchtime and was killed in a motor vehicle accident by an officer that ran a red light.
You can spend years and years fighting on the front line or doing whatever else is required as you serve your country and then you come home, where you think it is safe, where there is not a war, where you can relax and live a peaceful life and you go home for lunch, but never make it. Your new wife is left alone to try to pick up the pieces and make sense of life as we know it and life as we don't. It's interesting the pebbles that are thrown in our path as we make our journey through life.
