Stuck in traffic? A few wonderful minutes to relax and sit. Your car broke down after idling for so long? Ah, what a nice nudge to take a long walk the rest of the way. A swerving car driven by a distracted, cell-phone-wielding idiot nearly hit you as you were walking and soaked you head to toe with muddy water? What a reminder about how precarious our existence is and how silly it is to get upset about something as trivial as being late or having trouble with your commute!
