Everyone's been there - driving home from a particularly blood-boiling encounter with the crazy boss, nasty co-committee members, or ex-significant other. Unfortunately, punching the steering wheel and cursing at the indifferent windshield never seems to be as satisfying as hoped. After a few miles, you finally come up with that clever line that you could have ended the transaction with if you had just been quick-witted enough (or brave enough) at the time. You replay the scenario over and over again in your head, replacing the way it actually went down with how it could have went down "if only I'd just said…" Wait, stop the car. What if there was a way you could go back in time and say it?
