Training...
Everyone should be forced to have at least one job in their life where they have to take some form of mass transit -- if only for the occasional glimpse into the lives of other people. I got to overhear the guy sitting in front of me on the train this evening make a call to his wife telling her he was working late and then call someone I can only assume is his girlfriend and arrange to meet her (or him) for dinner and more... I almost felt like saying something, but what do you say, "Excuse me sir, I think its wrong that you're cheating on your wife?" Clearly, that would be convincing...
