I lost my keys once before time to leave the house. My dad, brother, and a friend were at my house doing and extensive search for them. We spent so much time searching that we ran out of time and called off the morning hunt. It worked out though because a huge squall line of storms was just an hour out and we didn't know that. It was before the smart phones were around and easy access to a radar. In the end the keys were in my pocket the whole time. I never told them till months later.
