Well, if you look at it that way!

I am a convent school product. In India and especially in my age this mostly meant you were instructed and were expected to command over "Queen's" english; UK english if you will. There was no cable and not much infusion of north american television or movies in our lives to know untill quite late that the world knew another way of using english as a language. That there was a websters to the wren & martin. All these years later I still have a problem with swallowing non-UK grammer and spellings. The s-to-z conversions still jar me!

 I have had in fact a lot of problems with the sounds that grate my sense of what correct grammer should be. It took me a while to get comfortable with texting what with all the abbrs and intializn. I am aware that how much ever I think I've gotten 'footloose' Iam still medival in that sphere!
I have a thing against rap and hip hop too. I dont understand it most times and even if I do, I dont always appreciate it [leave aside eminem for now]. My thoughts are immediately drawn towards 'kids listen to this kind of stuff; the music has influence and on kids at a very impressionable age; among other things it promotes, this is awful language!' And then when I hear things like "whys you gatta sit here?" to my request to a young one to take her feet off from top of my seat, I feel somwhat vindicated. Justification for my sense of pall for where is the language going also comes to me in bits and pieces when I overhear conversations in everyday life on the train, in the coffee shop, bus stand, etc

 Of course this could be just an "A-G-E" thing. But humour me, I am goin somewhere else with this. 

 I've always been fascinated with Shakespeare. Never really had a chance to study literature although I would have loved to. The DIY method of studying isnt as easy as it may seem. The language to put it mildly, needs efforts to understand. Its not an easy read.
My fondness for literature not being restricted to the english language, I am also an eager learner for Indian literature. The classic texts like the Geeta, Gyaneshwari being part of this personal quest as much as the yearning to know the substance of the vedas. Again, none of these ['ask aaenyyybody!'] are easy reading for a DIY project.
Another patch of passion: movies. I love movies and esp old movies the black and white kind. All and any language - providing there are subtitles! But the ones I can uderstand on my own without help are also not as lucid because the language isnt what is spoken today.

 Easy to decipher then that language evolves?  Is in constant process of evolution? Fair also to assume that literature and entertainment are important contributors to this process?
Can I then conclude that what I hear in the songs today and on the streets and in movies will influence the development of what will come tommorow? That for example shoulda, woulda, coulda will be proper words of choice? That if you liked it, then you shoulda put a ring on it would be obvious? 

 More importantly - if I find yesterdays' difficult to understand and tommorow's uncomfortable to be with, then am "I" the lost one?
