Hi
Welcome! I'm new to this site too. It's cool to find a novelist on here. I read of the article you linked; you sound like someone with a lot of interesting things to say. While I don't have any formal education in psychology, I do have a huge interest in it (which you can imagine, began when I grew frustrated of not understanding other people). So obviously I love to understand what makes people tick. Sometimes I find that I've even trained myself to spot traits in people, that others don't see at first, which surprises them; though I still have much to learn.
I understand what you mean by being overly blunt; I've had to learn to tone that down myself over the years, as well as learning people don't always want to talk about the topics that interest you. I've learned to drop hints, that may start a conversation, and leaving the ball in their court. There was one time, when I was feeling lonely; my sister urged me to try an online dating site. Rather than going on there to be romantic, and find a man, I would talk about things that interested me, in a very analytical sense. It wasn't until later, I realised how odd this was, and why no one stuck around for long, haha. After a while, I found that didn't matter to me, and I would use the websites to conduct social experiments, which I would inform people of. Some found what I had to say interesting for a time, but then also moved on. Needless to say, what I learned was valuable (who would have thought).
I too used to prefer being with adults when I was younger. My family often told me I was born a forty year old, but adults loved to talk to me. Adults who were double my age, would tell me that I was more mature than most adults that they knew. I was never able to relate to teenagers, which I always thought was odd. Night clubs, binge drinking, and all sorts of rebellious stereotypical behaviour baffled me, which is probably why my sister and I stopped being so close once she became a teenager.
