True story. You may or may not know that the thing that many americans do the summer after college is get an open ended plane ticket to Europe and a Eurrail pass and travel the continent. My friend and I got off from an overnight train with little or no sleep in Rome. He dropped his bags next to mine and said watch these while I go to the bathroom. A tap on the shoulder later with what could not have been more than a few seconds of me saying I don't speak Italian, his bag, with his documents, walked away. I had no idea until he came back and said where's my other bag.
