When I was ten, my mother worked all day so I had to take care o      my younger brother. At that time my little brother was about four years old and he missed mum all the time.
One day, after I had given him his dinner, he started c     for mum. He was so young and really needed
mum. So I d        him, put on his shoes, carried him on my back and walked out. Soon he f      asleep. About half an hour later, I found that he had lost a shoe while sleeping. I took him off my b       and put him down. I knew we needed to find that shoe, for our mother couldn't afford new shoes. We had to go back to find it, so I told my brother t    wait right there. A man heard it and stopped me just b       I walked off. He asked me, "You are leaving your brother here to find the shoe? What would you do if he is not here when you return?" I did not know h       to answer that question. He continued, "It's OK if you can't find the shoe, but it is not OK to lose your brother." Then he sent us to mum's workplace by taxi.
My whole life I have depended on（依靠） the kindness of many strangers, I feel regretful that I cannot find them and say thank you. I do not e       remember what the man's face looked like, but he taught me a lesson-people are m      important than things.
