i'll send you a paper i have on it. it's mostly academic stuff, but some of it is useful, especially the fact that ToM can be learned.
i had no ToM whatsoever for ages. i have learned it, but i still have to remind myself that not everyone else thinks as i do, more or less all the time. so, i have to deal with that intellectually, and tell myself that others think differently, even if i don't know/believe this within myself, inherently. if that makes sense.
