Do not leave your keys on a rack shelf

Yesterday was a horrible day for me. I lost my keys to my car and I was searching for them the whole day. It was a normal Wednesday afternoon when I was leaving my office and I went to the parking lot nearby where my car was parked. It was then when I realized that I do not have the keys to open it. I searched all my pockets and my briefcase but I did not find them. I was sure that I left them on the desk in my office so I went back to check. How shocked I was when they were not there. I have also checked other offices where I was talking with others employees and the cafeteria where I ate lunch. I did not find them either. The spare keys were in my house so there was no way that I could drive back home. Then I decided to calm down and to carefully think where I could have left them. I sat at the desk and I started to think where they could be. The suddenly I realized that the last time when I saw them was when I was trying to open a rack shelf in the server room. It was then when I used them to open the small door that stuck. So instantly I went to the server room and I found them lying on the rack shelf as I thought. I felt a big relief and I really do not know what I would do if I did not find them. Probably I would have to go home on my feet or travel by bus.
