Am I antisocial or just "programmed" differently?

In my experience it seems that the people that I can connect with are people that have many things and interests in common with. It just makes logical sense that people are like this. Sometimes I feel like I am very different than other people and when I hear someone bring up that I thought I was the only person in the world that agreed/likes whatever they were talking about, I start to get the feeling that I'm not so different and I begin to discover like-minded people. After I get to know that person for a while eventually I get used to their personality and ways. I can begin to predict their actions and what they would say to something. Sometimes people that you never thought you could be good friends with end up being some of your closest friends as you discover more and more about them and sometimes you may have a hard time connecting with people that you think that you have a lot in common with. Its wierd how this sometimes works out. Sometimes it can be hard breaking the ice and really getting to know someone for who they truly are. People have a way of putting on a "mask" and acting differently around different people. sometimes it may take a really ling time to break this ice, but once you do, its a really cool feeling. I know it can be hard to do this, but keep trying. You're bound to find someone that you can consider a close friend. Good luck :)
