I have searched through many trash cans and had many panic attacks over missing keys, but my dear sweet Dubelicious lost his keys the other day. Only problem is that he lost them while he was in the car.
He apparently went out to the car to look for some papers. He found the papers quickly, but then he couldn't find his keys. He took everything out of the car. He looked under seats. He checked pockets. He sat down in the front seat again exasperated and coming to terms with the fact he was going to have to call me for help.
Then divine inspiration struck and he checked the ignition. Yep, they had been there the whole time.
