One of the best stories I've ever heard about someone I don't know

So my roommate's coworker's roommate...

had her dog die in their apartment. It was a big dog. They didn't know what to do with the giant dead dog in NYC. They didn't have a back yard to bury it in and didn't want to throw it into the dumpster, so she decided to take it to the Humane Society to have them incinerate it or do whatever they do with their dead animals. So she puts the dead dog's body into a big duffel bag and took it down to the Subway. It was a really big dog and so she was struggling carrying it on the stairs. A guy saw her having a hard time and asked if she needed help. And she accepted. So he carries her bag onto the train and they are chatting a little while they are riding. At one point he says, "That bag is really heavy! What is in it?" And she answers, "...uh, some books...a computer..." and at the next stop when the subway doors opened the guy grabbed her duffel bag and ran off. She just let him go.
