lost briefcase

My car still has some bugs to be worked out. One of them is that the door locks are sticky. Curiously, when you lock the trunk all the doors lock, and visa-versa. I went to unlock the trunk yesterday, but the lock was jammed. I set down my briefcase behind the trunk. I then went to the passenger door, but it was jammed too. Finally I was getting mad and went to the driver's door. I had to fiddle a bit, but it opened. I got in and drove off. It was not until half an hour later that I looked for my briefcase. I looked everywhere, and it was lost. Oh yeah, I had left it in the road in front of my house. I was about ten minutes away, but went straight there. It was gone. I had some important stuff in there, a camera, my car registration, and just lots of personal stuff. I kicked myself silly, but there was not much I could do. The next day, as I was waxing my car for the 4th time this week. Once it is a few more months old it will never see wax again. I also swept out the back seat, and fallen on the floor, where I could not see it from the window, there was my brief case. I guess I had put it in the car after all. I love when problems solve themselves. I thought I had looked there.
