I'm trying to convince my digestive tract not to self-reset and violently reject everything within it, after that.
By which you mean...?
Is it lying not to tell (?) someone that most of my "highly developed social skills" (compared to some) are learned behaviors, learned by my imitating others, as closely as possible, echoing and reflecting their inflections, trying to understand how to intermix (quite cleverly, sometimes) assorted, diverse, but indistinct strains of vocal inflections with the various body languages, which are different for every social situation or for every perceived impetus, in order to create more precise two-way communication? ... or should I just let them keep on thinking that it is natural and that my lumbering efforts to "connect" are wholy composed of what is truly me and my thoughts?
Omitting information, though sometimes just as dishonest, is a different act, so technically it isn't. As is the case with lies, it depends on the situation and however you place your values whether it is justified. Nothing new, is it?
If there is no harm, you might just as well tell it. If it'd cause a change for the worse, just as disclosing your diagnosis in many cases would, then I'd recommend keeping it to yourself.
