Can you explain why you seem to be reading everything I say in the worst possible light? It comes across like you are intentionally trying to bust my chops, not understand my point.
I don't think I'm reading this negatively. I'm genuinely curious as to what sort of reaction would make you think they wanted to strip search your son. The only image that comes to my mind when I think of someone wanting to strip search someone involves a cop, a latex glove snapping on the wrist and a menacing look and that seems so the opposite of every experience in a pizza place I've ever had.
You are taking my remarks a bit too literally. And your experience in a pizza place and my son's experience are entirely different things. Coaching him on what to say does not solve it.
We have done a lot of reading and we believe he lacks prosody and lacks the ability to tone match. This is something other people are not consciously aware is socially important, but he routinely gets that reaction that is summed up by the phrase "I don't like your tone."
In contrast, I appear to habitually tone match without trying. This gets me read as incredibly deferential, which has a different social downside. So, one thing that does work is he and I frequently shop together, everyone knows I am his mother and people generally find me likeable. They eventually conclude "He's a nice, quiet young man." and quit having an issue with him being him.
