Responsibility is a unique concept... You may share it with others, but your portion is not diminished. You may delegate it, but it is still with you... If responsibility is rightfully yours, no evasion, or ignorance or passing the blame can shift the burden to someone else. Unless you can point your finger at the man who is responsible when something goes wrong, then you have never had anyone really responsible.
Chances are if you find yourself caught up in a political foofaraw at work, or in some family squabble at home, it's because someone else is succeeding in convincing you that his problem is your problem. The non-self-destructor recognizes this and as soon as possible, gives the sleepless night back to the person to whom it belongs.
