Personal morality varies from person to person, and even within a person over time. Some justify stealing other people's things in their minds one way or another, but still have a an ethical line they don't want to cross. Oddee collected stories of thieves who had a change of plan due to unforeseen circumstances, like the laptop thief who made off with data representing ten years of work for a professor in Sweden.

The professor had left his bag containing the laptop hidden behind a door in his apartment stairwell while he went into the building's laundry room. When he emerged a short time later, the bag had gone. It was returned shortly after, without the laptop. However, a week after the theft, the professor received a USB stick containing all the documents - which would have taken several hours to download again.
