Coming back to the extended stay hotel from my morning run, I went to open the outside building door but realized I didn't have the needed room key. I could have sworn I took the key out of my wallet and put it in my pocket. Hoping the folks at the front desk had arrived for the day, I went in the main hotel lobby, and was in luck, so I got another room key made.
After I got to my floor, there it was, laying on the hallway floor. My room key.
