A roommate went out to a bar with a friend one night, and a guy wandered in. They all started chatting, and the friend finally left when she saw that they only had eyes for each other.
When they parted, they really knew very little about each other. The roommate kept thinking about him, but since there was little info. exchanged, it looked like a doomed start. She finally hired a private detective, and armed him only with his first name, the color and make of his truck, and that he was working on a construction site in the Chicago area. The detective tracked him down.
They have now been married almost 20 years, and the check she used to pay the detective is in their wedding album.
