If you’ve ever had a laptop stolen or watched a hard drive melt, you know how devastating a data loss can be. A Swedish professor almost had the displeasure of discovering that feeling when his laptop was stolen. Then, a week later, he got a thumb drive in the mail, containing all of his data.

Yes, the laptop thief loaded all of the stolen data onto a drive and sent it to the victim. On the day of the theft, the thief also left behind the professor’s credit cards and some cash, all of which was in the laptop bag from which the computer was taken.

When asked about the incident, the professor simply told Swedish press, “this story makes me feel hope for humanity.”
