Speaking of the subject, something that I lost then got it back to me, it is my iPhone 5. Actually, quite important to me in my life at that time. You know, I bought that new product a couple of years ago when I was in university. More importantly, I got the financial support all from my parents as well. See, I told you. It is rather necessary to me then. I still remember that it was gone after a hard day of my study in the library. I even didn't know how to find it back after realizing it was lost. When I arrived at my dormitory, I found that I might leave the phone in the library. I was very nervous, kind of like I am tearing out my hair. I immediately went back to the library then tried everything that I could to find it. Some of my roommates did a big favor. We spent almost 2 hours in the library. Eventually, the supervisor of the library gave it back to me on the seventh floor, I mean, in his office. I was like a bit shocked since I didn't expect that things went smoothly in this way. Thanks to those great people. I appreciate the kindness and love from my friends and supervisor. They gave a hand to me. That is it.
