“The bottom line is that in those first years you either learned to trust the other, and the outer world generally, or you didn’t. If you did, your sensitivity remained, but you were rarely threatened into distressing long-term arousal. You knew how to handle it; it seemed under your control. If you asked others to stop doing something, they did. You knew you could trust them to help you rather than overburden you. On the other hand, one way that chronic shyness, anxiety, or social avoidance can begin is if your early experiences did not build that trust. It is not inborn but learned.”
