I'm just thinking of how so much of my thought processes involve a priority of things over people. Which at times can stick out in the wrong way with Neurotypicals.
Yet even my masking wasn't about what any one person did. I just tended to mimic group reactions. Smile when someone made eye contact with me, laugh when someone said something allegedly funny, and feign interest even when I had no interest at all with what was being said. - Gestures without any particular identity.
It would never have occurred to me to mimic any one individual. Go figure.
