Picking up a hitchhiker takes a lot of courage. You have no idea who this person is, and what their true intentions are. Some of the time, hitchhikers are interesting people with fascinating stories to tell. On rare occasions, though, these hitchhikers can create more trouble than not.
This person’s hitchhiking story started as one of those good ideas that seemed like it would be a great experience. After picking up the hitchhiker, they quickly realized their mistake. When the driver took the hitchhiker to their destination, they wouldn’t get out of the car. Luckily, a cop randomly came along, and the person told the hitchhiker they’d call the cop over if he didn’t get out of the car. The hitchhiker took that as a big warning sign and got out of the car. That’s probably the last time that person ever picked up a hitchhiker (via The Brainy Penny).
