Communication.....why is it so difficult??

I have been wondering about this for almost..... as long as i remember.....

I used to be a shy kinda girl.....not much into friends and socializing.Ofcourse, i had some very good and close friends always, who were real treasures. Some of those are still sticking around.

Well, back then people used to emphasise that words are important to communicate and if i don't speak up nobody will understand what i wanted to say. My understanding was - It's almost visible on the face of a person what he 'needs'....words are important only to bring people together.
So, gradually as i grew up and reaslized my theory doesn't work, i tried adopting the 'mass theory'. And , i have been speaking up for all my needs and views for almost a decade now...i adopted it so well that it has become my second nature to speak up what i think. But lately , i am becoming more and more aware that -even words don't work!!!!!!!!!!!!

So, if words don't help in communication, wat does???? I guess it's the PEOPLE. Some people just communicate well and some don't. And, it's not necessary that a good communicator is always so.....even he might not be able to communicate with some people.....well, then the 'theory of communication' suggests there are people who can be 'communicated with' or people who 'can't be'........And sometimes they are even proud of being 'unavailable to communicate with. So , it must be that they don't need a society or friends or anyone for company. But then , i have never seen any one who don't have even some friends or family to talk to.........

Well, once somebody said to me 'If one doesn't understand your silence , he'll never understand your words' .....And with time i am experiencing how true these words are!!!!!!!!!!!!!

(I hope i am being clear.....again words are needed and i am now increasingly aware i am not good with words!!!)
