Solitude
As a boy, I spent a lot of time alone in my room with the door closed. I don't remember feeling lonely. It was peaceful. I occupied myself in many ways: playing with my toys, drawing, reading, using my imagination. I was an only child until I was twelve, so I spent many hours this way.
In the turmoil and chaos of elementary school, things didn't go well for me. I wasn't popular and I didn't know how to interact well with other children, but I tried really hard. I lacked social skills, so I got picked on and bullied. I was scared and cowered, which didn't help. That environment made me appreciate the solitude of my room for what it was, a place of peace. A place where I didn't have to worry about the frustration and conflict of interacting with other people; something that I clearly wasn't good at no matter how hard I tried.
Some people have a knack for personal interaction. Other people want to be around them, they are popular. Some people are gifted in getting what they want from other people, be it money, food, sex, jobs, influence, power, a multitude of things. They know the secrets to human interaction. After intense study my whole life, I've never figured any of it out, and I'm still really bad at all of it. I have come to understand that I probably have some "issues" and "flaws" (read: psychosocial deficits) and perhaps I could work on some things to improve my abilities, but I will never be very good at interpersonal interactions and at least part of that is not my fault.
