I used to wonder what my other family members were talking about with so much interest, wishing I had the courage to go over there and find out. Then I would go over and find out, and they were talking about the most boring and horrible subjects that I couldn't tolerate for more than a few minutes, and I went back to sitting alone in my room, disappointed.
That's my version of the guy looking for pieces of paper on the floor.
Eventually, I learned the concept of categorizing interpersonal communication, and I became able to remember why I wasn't around my family so much, and I became content to close my eyes and think happy thoughts. Even though they seem so joyful and so happy to interact, it's not something I'd ever want to do with them.
Now, I just rush out to them from time to time and interject in the moment that happens when someone barges in on a conversation, and I am on my way out just as quickly. This behavior seems to intrigue people and reduce alienation effects, in my experience. If I were to try to patiently spend time with them, I would only end up become aggravated, and make everyone upset, burning myself out in the process.
