I've always known that I'm introverted, it has only been recently that I've gotten familiar with that term. This realization doesn't make things easier, except in the sense that knowing that people may start to understand through these blogposts. It's frustrating when you can write these things out, but get flustered in conversation and It's been a long and arduous road so far, being ridiculed for being "shy" or "anti-social". I only know that it's been by God's grace that I've put up with it.
I'm excited, though, because I've recently moved to a different state and have met some really cool people and really enjoy being "social". To others, it may not seem at all that I'm being social, and therein lies the conundrum of the introvert. An introvert being "social" usually does not look at all like their having fun simply because an extroverts definition of fun is that you should look gregariously involved and talking to everyone they contact, laughing and perhaps making jokes and being popular and maybe the center of attention. A lot of introverts like to go to social gatherings and be around people, for a limited time. It's just that they may seem very aloof and seemingly shy, but they are having as much fun observing and processing everything around them in their heads. Along with that is usually the anxiety of going up to people and talking and trying to keep the conversation going, (and that's another story) but most fun for an introvert is found in their own head.
This is why a lot activities that we find fun are thinking activities. It may take us a long time to start to talk to someone, but the real fun for us is the thinking that is involved. Of course, there are many types of introversion so this isn't true for every introvert.
