I absolutely missed some social developmental windows, somewhat like the kittens who, never exposed to horizontal lines during a critical point in the Blakemore and Cooper experiment, were unable to perceive them later on. Nothing I have been able to do in terms of reading, groups, exercises, and the like has been able to grant me the easy camaraderie that comes readily to others. Instead I am typically watchful and quiet, on the periphery of any group. Carnegie, Toastmasters, and all of the glad-handing can provide at best a kind of thin simulation that never takes root for me. I have faked it and been unable to make it, leaving me with a somewhat guilty fear that any charm I may have would be greasily like that of any garden variety psychopath.
Perhaps the most "positive" thing to come out of it would be near-schizoid levels of self-reliance and an ability to acquire local accents to better fit in.
Some kids get over it, some ... do not.
