Lost and found

The door bell rang while I was in the kitchen so one of my roommates ran to get the door. Minutes later, she called me to the door as well. When I got there, a man with a dog asked me if any of us had lost an ID. I replied that we hadn't but if he would show me the ID, I could try and see if I knew the person.

So the man pulled out the ID, and it turned out to be mine. I was so shocked; I seriously thought my ID was still in my backpack. I told the man that the ID belonged to me and how thankful I was that he had found it! I asked him where he found my ID.

He explained that he found it while walking his dog. He recognized it as a student ID so he picked it up. He said I had dropped my ID on the drive way leading up to my apartment. Since the complex I lived in was primarily leased to students, he had gone door to door asking if anyone had lost an ID.
