For me, i also find myself not being shy around some people. Mostly people who i know are friendly and accepts me for who i am. They are generally kind people and usually talk/approach me first.
I certainly think that we are more than our shyness, because we tend to hide our true selves due to shyness. There's a lot of things we don't show to other people. But once we become comfortable with some people and the shyness goes away, there's a lot more for them to discover and hopefully appreciate.
Doing and saying the wrong things most of the time 24/7. Being me means having to endure people not liking me.
