I have to agree with what you've said. It pretty well applies to me, though 20 or so years of retail selling has taught me how to control it all. Step outside of work and the masquerade is off though.
I figure if a person is gonna take something that I may say that serious, then probably they're too serious about things anyways, and *shrug* tough titty for them.
I've gotten away from expressing my humour with others, especially those that aren't close friends, that know me well enough to know if it sounds like it's supposed to hurt, it's a joke... period.... I guarantee you that if i'm trying to hurt your feelings you'll have no doubt whatsoever what i'm doing... there won't be any question of "was that a joke, or was he insulting me?" A spade is a spade, and I'll have no part of making it sound pretty when it ain't.
So for the most part, i keep my weird convoluted humour to myself. I do have other friends that understand it very well, even though they're NT's... Though to be honest, the one that understands it the best... Might get him to take the aspie test, cause... though I've never thought about it till now, and he's always saying that he thinks he's ADD ... Perhaps.... I'll have to give him some stuff to read anyways.
So take this as a warning, my humour WILL be sarcastic at time, and not always easy to identify as a joke.. but if i'm insulting you... believe you me, You WILL know it!
