Article: This story took place a long time ago. But it has been repeated time and time again. Everyone is moved by the true story. An old man was knocked down by a car and was taken to hospital. He was badly hurt, and during his few returns to consciousness, he repeatedly called for his son. None knew where his son was. A dirty letter was found in his pockets. The nurse learned that his son was a solider inprefix = st1 /North Carolina. The hospital called the Red Cross offices to find the young man. The young solider was rushed to the airport in time to catch the plane. It was evening when the young solider walked into the hospital. A nurse took him into the bedsides of the old man. "Your son is here," she said to the man. She had to repeat the words several times before the old man's eyes opened. He dimly saw the young man and got great comfort. He reached out his hand. The young solider held the old man's hand and offered words of hope. All through the night the young solider sat besides the bed. The nurse offered to watch instead of him for a while. He refused. At dawn the old man died. The nurse started to comfort him but the solider asked her, "Who was that old man?" "He was your father," she answered. "No, he wasn't. I never saw him before." "I knew right away there was a mistake, but I also knew he needed his son, and his son just wasn't here. I realized I was needed. So I stayed."

Article: Like many new graduates, I left university full of hope for the future but with no real idea of what I wanted to do. My degree, with honors, in English literature had not really prepared me for anything practical. I knew I wanted to make a difference in the world somehow, but I had no idea how to do that. That's when I learned about the Lighthouse Project. I started my journey as a Lighthouse Project volunteer by reading as much as I could about the experiences of previous volunteers. I knew it would be a lot of hard work, and that I would be away from my family and friends for a very long time. In short, I did not take my decision to apply for the Lighthouse Project lightly. Neither did my family. Eventually, however, I won the support of my family, and I sent in all the paperwork needed for the application. After countless interviews and presentations, I managed to stand out among the candidates and survive the test alone. Several months later, I finally received a call asking me to report for the duty. I would be going to a small village near Abuja, Nigeria. Where? What? Nigeria? I had no idea. But I was about to find out. After completing my training, I was sent to the village that was small and desperately in need of proper accommodation. Though the local villagers were poor, they offered their homes, hearts, and food as if I were their own family. I was asked to lead a small team of local people in building a new schoolhouse. For the next year or so, I taught in that same schoolhouse. But I sometimes think I learned more from my students than they did from me. Sometime during that period, I realized that all those things that had seemed so strange or unusual to me no longer did, though I did not get anywhere with the local language, and returned to the United States a different man. The Lighthouse Project had changed my life forever.
Answer: His university education focused on the theoretical knowledge.

Article: Every day as I drove through town, I saw a one-legged man going through the dustbins next to McDonalds looking for food. It was only a month before Christmas, starting to get cold and I could not help thinking about him. So I bought a brush, pack of cigarettes, cans of fish, and then I added a blanket and sweatshirts. I made a box up like a present and went in search of this man. I saw him hobble away from the dustbin. I pulled over, took the box and went up to him. I said, "I would like to give you a Christmas present, there are some food items in here and some things you might be able to use." He sidestepped around me and said, "No, thank you. I just had lunch. I don't need anything." Then he hobbled on down the sidewalk, leaving me standing there in tears. I took the box down to a little shop that gave things out to the poor and homeless and told them what had happened and asked them to give the box to someone who could use it. The person there told me not to be upset and let my feelings be hurt as I was still crying. I told her I was not crying for me but for him because what I had done took away his dignity by treating him like a person in need. I was so ashamed. A few years later I was able to volunteer in St. Anthony's Dining Room in San Francisco. These people had to stand in line for up to 6 hours to receive the only food they will get. We took one tray of food at a time, and treated them as if they were in a restaurant ordering a meal they were paying for. From this I learned a great lesson. Accepting help is sometimes harder than giving it.
Answer: Because the man was looking for some food.
answer:
Why did the author buy something for the one-legged man?
