Fortunately for me, there's that last 2% with whom I'm able to just click with almost automatically. I've only met less than a dozen people like this in my life.
I remember years ago watching a "making of" special on the X-Files. David Duchovny was talking about his character Mulder, and relating it to a man he knew who was socially awkward, but had a fantastic wife. The man referred to his wife as his "human credential" - she was sufficiently fabulous that the people they knew figured that there must be something to him because she saw worth in him. She was proof that he was a worthwhile human being.
I tend to feel that way about my 2%. Those few people I can actually talk to vouch for me, and in time familiarity serves as a substitute for normal human behaviour.
