I think that my brother learned these skills. As a child he seemed different. He used to sit in class writing pages and pages of numbers. He was always 'numerical' if you know what I mean. He did applied maths and theoretical physics at college, but struggled with English as he had Dyslexia.
HOWEVER, at some point about 17, he realised, ok, all that is expected of me is to say "Hi, how are you?", is that it? Ok, and to stand still and nod a bit, and listen to the reply? \is that right? And smile a bit, laugh sometimes, hmmm, OK< and then I think of question that shows I've been listening?
He had to break it down. Effortless banter between two chatterboxes was analysed in a scientific way, and then copied!
He does it quite naturally now
Hope that helps.. My own son has inherited that type of brain too i think. But I am not as worried as some of the other parents are. A little of course.
