I don't often lose things and I'm especially careful with money, so I was quite surprised when I reached for my wallet and it wasn't there. (79) At first, I thought it was possible that I could have left it at home. Then I remembered taking it out to pay for the taxi, so I knew I had it with me just before I walked into the restaurant. I wondered if it was possible that it could have slipped out of my pocket while I was eating dinner. Thinking about that possibility, I turned and walked back to the table where I had been sitting. Un fortunately, there were several people sitting at the table at the time, so I called a waiter and explained to him that my wallet had fallen out of my pocket while I was sitting at that table a few mi nutes earlier. (80) I had the waiter go over to the table to see if my wallet was on the floor. While the waiter was looking for it, the manager of the restaurant came up to me and asked me if anything was wrong. I didn't want to get a lot of people involved in the problem, but I knew I had to get the wallet back. I told the Manager what had happened. He had me describe the wallet to him, and then he insisted that I report the missing wallet to the police. I told him that I had an appointment with my doctor in just a few minutes. I explained to him that my biggest worry at the moment was how I was going to pay the check. He told me not to worry about that. He had me write down my name and address, and he said he could send me a bill. According to the passage, we know the writer ______.
