for me it's not insincerity the words are just meaningless I can't give you feedback about a compliment because it doesn't mean anything to me at all .Oh yes I do! I can recognize how he expresses his caring through "acts of service" and do not need him to compliment me. I think I fully understand how important his actions are, more so because he has a wall up and lets me in. That's not really my issue. I'm upset that if I compliment someone, like on this forum, that I will be perceived as insincere and manipulative when I am being as sincere as I know how to be. I only compliment when I believe it to be true and feel the feedback would be helpful to the person I'm complimenting. But maybe feedback is only helpful to NTs and not aspies? I view sincere feedback as a way to correct distortions in one's self image. If someone has no need of feedback for this then that's fine. But sometimes I just like to express appreciation of someone's abilities, behaviors or whatever. I feel like I'm digging myself into a hole of justification here so will stop. (I want to steal a Fridge tactic and say "You're all awful so just go home." ) (see Fridge, I'm learning your bad habits XD)
autism is logic based,because I panic so much I'm pleased by things that stop the panic !the more I'm panicking the smaller my vocabulary becomes !,it's a form of dementia but this dementia is almost curable because your vocabulary can return when you panic less.
somebody complimented me on my hat !but I was more pleased because somebody had actually talked to me and didn't give me a patronising tone.The person asked where I got the hat.
