Z, I fail to understand you at times. When you are in a new situation, you become extremely shy. You are quiet and hang on to the person you're familiar with. Once you are comfortable, you are good to go. You do not need any one around. You love to talk and go on and on.
I guess that holds true for all of us to an extent. With you, its two different people all together.
Message for the day: I think, it is good in a way if you take your own sweet time to open up.
