Politico has an article on Chelsea Clinton the enigma. She, the authors observe, is guarded.
But, hey, who isn't.
In this era of lawsuits, social-media flaming, and just the usual spitefulness, most of us have certainly learned to be guarded. The old-fashioned term for that is "spin." In fact, we consider the unduly open as fools. It didn't take law school to impress on future lawyers the importance of being totally self-editing in real time.
That's exactly why so many of us are chasing a shot at intimacy through dating services like eHarmony. In intimate relationships there is supposed to be the safety to drop our guard.
When the relationship goes kaput, that's why we hurt so much: We had let down our guard. Allowed the other to experience the real us. And then there's an ending.
In dealing outside of intimate relationships, we have to learn to decode what the others in business and even in our social life might really be indicating. And they do the same with us.
Those who have "opened up" frequently find themselves needing a lawyer. That includes disclosing criminal activity during meetings of Alcoholics Anonymous. Paul Cox found that the hard way.
