You’re walking along train tracks with your dog and you hear a train approaching. Nearby is a guy jogging down the tracks with his mp3 player turned up so loud that he can’t hear anything. Your dog gets away from you and gets his leash caught in the tracks. You see a train rapidly approaching, the guy doesn’t hear it and you can’t save both the guy and the dog. Who do you save?
Instinctively, I’d go for my dog. Yeah, I know. I'm a horrible person. *shrug* I really like my dog.
