I am going to sound a little Boy Scout here for a second but, it made me feel good so I am going to relate the story.
I was walking on campus earlier today and came across a Flash Drive hanging on a fence post. My first thought was devilishly: "Cool I just found myself a new Flash Drive!" When I flipped the thing over however, I found that much to his credit the owner had put a label with his email address on it. So, I stuck the thing in my pocket and brought it back to the office with me.
I sent an email as soon as I got back and, within an hour, had received a response. We arranged a meeting time and location and within another hour he had it back in his hand. He was understandably very happy to have it back and the smile on his face was priceless.
Remember: Do a good turn daily.
P.S. I would like to thank the other good samaritan in this story; the one who hung the drive on the fence post, instead of stealing it, when they found it.
