FS Pogue - Okay, even though I said I wouldn't "debate"... Just read your post again, and I have to respectfully disagree with one main thought. This is not a matter or right or wrong, of course, but just the way I personally choose to lead my life... I don't think relationships can always be dealt with on a quid pro quo basis. You say, "Relationships that require maintenance but proffer no lasting, significance benefits are waste of time." Not necessarily. I don't consider my investment in people the same thing as my investment in the stock market (not that I have any investments in the stock market). Sometimes with people there is no "significant benefit." So what? Perhaps that's where karma comes in. Eventually it comes back to you. The good that you do, as well as the bad. I try to be a "good" person - sometimes that's not as easy as walking away and "preserving my energy, time and emotion," but I try. I don't always succeed -- and frankly, I don't always try - but we can strive, can't we?
(And yes, there are people - relatives, even - whom I have cut out of my life for good reason. I'm not Pollyanna, far from it. My only link to my long-dead father, for example, is his son, my half-brother. I have not had contact with him in decades, even though he wants to have contact.)
