Many Outgoing people are afraid to be different, does it mean Shy guys can be braver?

Although us shy antisocials are afriad of talking and being put on the spot, sometimes we do other things that outgoing talkative people would not dare to do in public.

For example, making faces. walking in different unusual ways, walking with eyes closed just for mental practice, skipping( like little kids do), pouting like little cute kids even if you’re a grown man,
I do all of this to my self when i go out walking or jogging and people see me and i don’t care. I do it for my self. I do it at the public park, in the street, etc.

And i don’t feel shy about it at all.
But i see outgoing loud people and when they are away from their group of friends, they never do this stuff. They are afriad to be different in this way.

So I think, social butterflies, get confidence from the group. but with no group many times, they are weak just like us shy’s.
