阅读理解 While I was waiting outside my wife's office building for her to get out of work.I saw a bum (流浪乞丐) coming my way. 'I h ope he won't ask me for any money, ' I thought. He came and sat in front of the bus stop.After a few minutes he spoke.'That's a very pretty car, ' he said.He was in rags, but he had an air of dignity (尊严) about him. I gave him a smile and continued cleaning my car. He sat there quietly as I worked.The expected asking for money never came.As the silence between us widened, it seemed that a voice inside me said, 'Ask him if he needs any help.' 'Do you need any help?' I asked. He answered in three but meaningful words that I shall never forget.We  often look for wisdom in great men and women, and we expect it from those of higher learning and achievements.I expected nothing but an outstretched (伸出的) dirty hand from him, but he said three words that shook me. 'Don't we all?' he said. I _ was _ feeling _ high, successful _ and _ important _ above _ a _ bum _ in _ the _ street , until those three words hit me like a shot. Don't we all? I needed help.Maybe not for a bus fare or for a place to sleep, but I needed help.I reached in my wallet and gave him not only enough for a bus fare, but enough to get a warm meal and shelter for the day.Those three little words still ring true.No matter how much you have, you need help, too.No matter how little you have, no matter how loaded you are with problems, even without money or a place to sleep, you can give help. Maybe God looked down, called an angel, dressed him like a bum, and then said, 'Go to that man cleaning the car.That man needs help.' Don't we all? 1. The writer was near the bus stop________.
