Inoculation can be fun

Whenever you run into a devil, be sure to get up close and greet him. Ask what he's selling and what he's taking in exchange. You don't have to shake hands. Ask only those questions, take away nothing less and nothing more than answers to those questions, listening only for those answers. He may tire of you before he is willing to be honest...that then is your answer.

That is the best way to avoid being one of those pious losers who, when faced with a tough choice, can't do better than the ancient abdication of responsibility: "Better the devil I know than the devil I don't know".

Not sure you'd know a devil when you saw one? Then you'll do well to fall back on a bit of advice from the Talmud:

Say little and do much; and receive all men with a cheerful countenance.

-Shammai
