阅读理解 After researching the history of the Vietnam war, I called my mom and asked her if she knew anyone who went to Vietnam that I could interview. She thought for a while and suddenly remembered that she has a cousin who is a veteran of the Vietnam war. She says: "I know this man since I was little. We were very close friends in high school. He was one of the greatest athletes of the school. You can not imagine how good and fast he was. Well, he was ranked number 20 in the country for being an outstanding track and field runner. But now, those things are only memories." After hanging up the phone, I immediately called him and introduced myself. He was in a cheery mood at the beginning of the conversation, but as soon as I began to question him, his attitude changed. "What happened in Vietnam?" I asked. There was a moment of silence on the other line, and then he said that he was willing to tell me about Vietnam. He basically said that he was drafted when he was 20 years old and that the two years he spent there are a part of his life he would rather forget. He said, "The problem is that you will never imagine how much suffering and pain I saw in that place." There is not one book, article, or encyclopedia that can really describe the human disaster that took place in Vietnam. There is nothing worse in this world than killing a man who you know has a family; destroying their future. It is very sad, but it is the truth, and it turns more complex when you realize that you were part of that truth. When I returned to Puerto Rico, it was a total disaster: young kids without fathers, wives without husband. Most of those who made it back are insane or have no legs, like me, or no arms. I was praised because of my bravery and other such things, but for me, that was and is pure nonsense, because that war decided my future, decided the future of my family. I, now, am just a veteran who never went to college. The thing that bothers me the most is that the people who decided to fight will probably never know what it is like to kill a man, or feel pain and suffering from hunger and the absence of love. In war, every minute you are fearing because the only thing you have in your mind is that if you don''t kill first you are going to get killed.
