I'm really interested in the "whys" of social interaction too, and have been fixated on "figuring people out": their intentions, motivations and perspectives, ever since I learned of my diagnosis as a teen. When in a social situation, I'm always thinking about other people, how they feel about certain things, and how they would respond to certain situations.
In general, I try to make myself stand out as less as possible by studying how people act, recognizing patterns in their behavior, and then attempting to replicate these patterns myself. However, I'll still maintain parts of my individuality depending on who I'm talking to. For example, I'll talk about a particular topic or display a particular sense of humor with people I know are interested, and will steer away from it with people who I know are not interested. I feel that it's really impossible to be truly yourself when you're around other people as you have to consider the other person you are talking to and be able to predict how they will react to certain things. I engage in a lot of perspective taking...it's truly a learned skill which requires a bit of an ability to read peoples reactions to things.
As for the situation above ^, I would see this as a subtle hint that the kids should be more polite/respectful...hence the positive change in behavior once you were more firm with the kids. Some of the messages conveyed by people are very subtle and this is where I think many people on the spectrum miss a lot of information.

Given a “tentative” diagnosis as a child as I needed services at school for what was later correctly discovered to be a major anxiety disorder.
This misdiagnosis caused me significant stress, which lessened upon finding out the truth about myself from my current and past long-term therapists - that I am an anxious and highly sensitive person but do not have an autism spectrum disorder.
My diagnoses - social anxiety disorder and obsessive-compulsive disorder.
I’m no longer involved with the ASD world.
