@hawkeye10,
Nah, my mother was the shy one who fostered my shy scaredy behavior, undoubtedly not on purpose. I sympathize more with her now than I've done for decades.
I seemed to figure out on my own, not sure when, a gradual glimmer over years, that shyness is a kind of nice sheen on a possible passive aggressive cockroach. Not that all shy is bad, but...
Something made me start thinking more of other people and what was going on with them than my being nervous about talking. I think it was a combo of actually relating to people at work (others have lives!! lots of stories there starting with the hospital cashier who made me choose a horse at Hollywood Park) and a psych 1A class by a fellow who is now, I think, eminent, or is in my mind. Plus, of all things, reading.
I spent a lot of years waking up, and probably still am.
