For someone that must use "big words", and had trouble dumbing it down, you did REALLY well in your last post!
Arbitrary and dismayed COULD be considered "big words" by some, but I doubt it. Try them out. BTW many words don't seem so big once you are in highschool or above. Still, people that don't understand words like dismayed are probably used to hearing "big words". Hopefully, they will be reticent("big word"?) regarding their deficits, and inclined("possibly"?) to research it.
Personally, I think there is a limit to how much it should be dumbed down, and you are probably at that with your last post. Also, I would have used reluctant here instead of reticent, as it is a more common word, and maybe would have said "decide" instead of inclined, as it may be a bit more common. Still, all of the words you used, and the ones I used here, pale in comparison to some I have seen on this forum, and most of those weren't too bad.
It is a sad state of affairs when such a simple post could be considered so haughty("possibly"?).
It IS ironic. I was once told I was using big words when I said things like Kilobyte or RAM(circa 1980)!
As for the "body language"? If I ever get tested for AS, one consolation will be that I could use it to defend my inability to discern such garbage and prove that any "signals" I flash are totally WRONG! That much IS fact anyway. Seriously!! !! There ARE books on body language, and I have done polls and found they are totally bogus. People WILL do things with their face to show emotion. That is a given. Even THAT isn't that reliable, as shown by the face reading tests.
Your time WOULD be better spent elsewhere!
