An unforgettable experience Everyone maybe lost something in life, and some of them might find it in the end when the others didn't find it till now.For me an experience remained so impressed that I can't foget it all life. In the last semester I studied in Russia as an exchanged student. The city where I lived is a tour city, And there were lots of thieves in streets and on buses. One day I went to the bank in order to pay my dormitory rent. When my friend and I went out from the bank, I touched my pocket unwittingliy and suddenly found my phone lost. At that time I was a little shocked and was sure that it must have been stolen, because phones from my three friends had been stolen before this in the city. But soon I recovered and asked my friend to call my phone immediately. I began running along the street, looking around and searching anything unnormal around us. Five minutes later, unexpectedly one middle-aged man came to us, holding one phone, asking whether it was my phone, I excitedly said and nearly cried out, "yes! It is!" " OK, it's so great that I found you, I just noticed a strange man running very quickly, holding a mobile phone. So I caught him. He handed over this phone and escaped away so fast." He explained it at length. I was at a loss what to do, just saying thanks again and again. He told us that he still had some affairs to do and left. I was so touched, and it was long before I calmed down, I was so lucky for meeting such a good man. What's more I learned from this experience was that we should be prepared to help others anytime in our life, and you maybe don't know what you can bring to others,
