This is not really a tip on how to accomplish your desired goal but a self-incrimination of my own attitude. Now that I'm retired I don't have to deal with the NT world as much as I did when I was employed. Having said that, when I am out in public which is primarily NT dominated I really could care less about any of these people. Reason being hypothetically speaking, when I pass through a check out line and the clerk's ONLY spoken words are, "Have a nice day" I simply realize that these people are actually frauds and they are "masking" their friendliness. They don't want to be there as well as I - but for different reasons. Chances are I won't have to ever confront this person again soooo... I could care less about the outward impression that I may be portraying to this person. Neither do I feel guilty about my demeanor. But that's just me. I am somewhat bitter at the whole NT world for the way I've been treated all my life. But I must confess that not all NT's are this way but for the most part, this hypothetical example is a common occurrence. I try to model my demeanor after the individual that I am dealing with and mask my behavior to match. When some of these NT's "pick up" on my social tactics, most are stunned. But what I have done is turned what guilt most people believe I should experience back upon them as their own reflection. I am not really sure any of this makes any since but - well that's me.
