Puzzle of connectivity

There had been a lot of first for me in Chennai, be it my first job, first yet to be received salary, first boss, first paid project etc etc. but the most interesting amongst all the firsts had been the first prepaid connection. In Delhi I had enjoyed the luxury of having an airtel post paid connection which provided me with seamless connectivity throughout. (I am not paid for writing this rather I am just a satisfied customer) Well the phone was more of a luxury to the people around me then it was to me as they could always get a phone from which they can make a call when their own balance runs out. I am not accusing anyone of misusing my phone but certainly many would agree that it acted as luxury. My monthly bill was around 300-350 which being a constant phenomena was always counted in my mind while forecasting the monthly expenditure. But when I got hold of prepaid connection, this estimation went for a toss!
While writing this, I am a month old in Chennai and well had been using prepaid services for a month now. The total expenditure so far including sim card price had been just 90 rupees!!! And it is not the case that I have someone with a post-paid connection whose luxuries I am enjoying, neither do I have got an access to some landline which I can use without paying. In-fact the expense would have been around 30 bucks lesser had it been a normal month and not the first month in Chennai, when you need to inform everyone for the first two weeks that you are safe and have started enjoying in Chennai (at least one can pretend to ). Though this is a good thing but it has made me think more deeply about it (which is the work that I enjoy). I realized that my entire talking time on phone in whole month is lesser than what the people around me do in a single day. And mind you I am not talking about the telecallers or some other voice processing professional but is talking about the my friends who work along with me at the same office. When one of my friends recently called me, I also realized that after initial few common sentences whose answer I know even before asking, I had nothing else to talk about. It it not the case that I am the silent type, rather I belong that category of people who are difficult to stop once they start talking, but still I had nothing to talk, and let me be clear that the friend was not a female, else I would have taken the refuge under some other obscure reasoning, but still I couldn't talk not longer than a couple of minutes. I had always been inquisitive about telecommunication and it was not the technical aspect of its functioning rather the other aspect which had remained a flummox to me. I am talking about the whole purpose of calling and the content the people talk about. I personally have called anyone when there has been a need. There has been calls to people whom you had not been in touch for long, but that is once in a year. I do not understand what to talk to anyone, if I would have met the person say a week ago or had talked within a week or maybe month, depends upon who the person is. But when I see people spending hours talking to same person virtually everyday as if it is a prescribed ritual which should be done unfailingly else one would have to bear severe consequences. Though I am a highly talkative person but still I can't even imagine to generate such a high volume of content on daily basis and still not to bore the other person. There must be a strong mechanics which work behind this content generation that I am not aware off but definitely want to have a glimpse. But alas no one shares the content, had there been someone who would have documented such hourly sessions for whole month, believe me I would have read the whole log maybe for tips as well as for quenching my inquisitiveness.
I have written this post for few purposes, first is that I want to communicate to all the people who know me that if I don't call you or talk for not more than two minutes ,when you call then please understand my inability.I want to talk but I am not able to talk. Secondly I request all the people who are reading this post to type down the content of one of their such talks and mail it to me or if you have speaker phone, please record it and upload it somewhere, with all the references to names beeped out. It would help me a lot to understand this whole thing and why do I care to understand this, well that's a question to which even I don't have an answer.
