And nobody helped him and he didn't know how to go on living. It was a very cold winter night. The old man couldn't go to sleep. He had been hungry for two days and it was so cold in his room that ice could be seen. He had to get up and began to run in the room until he lay down on the floor. The next morning he had to beg from door to door. He had been to a lot of cities and knew a lot. Once he came to a village, but the villagers were all poor and couldn't give him anything. He was too hungry to go to another village. He thought hard and found a way. He came to a police station and called out, "Hitler is a foolish pig!" Out came an old policeman at once.

Question: Article: My grandfather lived only half a mile away from where I grew up in New York. Every day, he would walk down to our house and bring my dad newspapers. Along with the papers he would bring a small bag of treats for my two brothers and me. Western New York had terrible winter weather: rain, sleet , or even 3 feet of snow. Even when he was 81, he still walked the half mile every single day. As a child, I looked forward to the daily treats, but now I'm older and I realize he braved the rough weather each day just to see us smile; I now value that more than anything else. My grandfather touched many lives. A woman who had been in hospital for five years told me her story. She said my grandfather would visit her twice a week at her home: to read to her, play bridge, or just chat. It lasted for years without stop. She had few visitors. Even a _ who had traveled by getting free rides from passing cars told me of my grandfather's influence on his life. My grandfather had picked him up for free and took the traveler to his home. After learning that the man was homeless, my grandfather gave him a place to stay. The man told me that no one had ever been so nice to him. He later found a job in a supermarket. I was touched, but not surprised to know all of the touching stories from which I understood my grandfather's selflessness. I have since tried to learn from him to help others. Although he died years ago, we still respect him.
