When I asked what was going on, He answered:
So many years ago, I fought in World War I. At some point, I saw a German, he saw me, we both aimed at each other but he was quicker and shot first. He missed me. In shock, I just ran away, never to see him again… or so I thought.
You see, some years later, I was fighting in World War II. I was on the battlefield and saw that very same German. I aimed at him and he did the same. Once again, he was quicker and shot first. And once agin, he missed me. The reflex to run away once again saved my life.
That German man just sent me a letter. He says “I miss you a lot”.
