I totally hear you both- silverhaze i can totally relate to you. i have always been like this. on the introduction front i often just feel the energy of the person and what they're like and I know wether I like them or not or wether Ill get along with them or not based on that. I can learn their name later :P and i dont 'need' to talk all the time - I know and sense things and dont need to fill the air with talk about all this 'rubbish' that everyone talks about. i listen to what people say and its just about nothing most of the time. I want to talk about 'meaningful' 'intelligent' things but when I come out with anything remotely knowledgable people dont know what im talking about or dont care.
when I do talk to anyone, I always get pictures or words of what they're going to say next or just know what point they're trying to get across - I used to think i thought of the idea first before I realised i was picking up their thought train!! I generally understand what people are saying exactly, and If others in a group dont get it, I always explain it to everyone and the 'speaker' says 'exactly! thankyou!'.
