Well when I was a kid I was practically mute, yet I still had a couple close friends. Around them I would get extremely hyper and crazy, as though I had to make up for the lack of talking I did all day. I was always very shy as soon as we went out in public or anyone else was around though.
I did feel a lot more social back then though. I was really sad that my shyness was holding me back. I felt like I had a great personality and no one knew it. I wanted to meet people and get out there. I've changed a lot in my thinking now.
