open letter

I was going through many words few minutes back, just a good past time. Words which are so powerful for me tonight that i get it first whenever i start thinking about words. The phrase which came in my mind is open letter. Open letters are supposed be very open, like the way sky is open . The thing about open or closed is really interesting. Open belonged to those kind of concepts even whose opposite can not be concretely defined. Both are related to each other. Anyway i have written few not so opne letters and one opne letter in my life, and they are so open that it wont come in opne air in their life .
Or may be that album of anjun dutta "priyo bondhu " , where there were so many open letters, between two completely disconnected people living far away from each other. Though i find the album very unsmart now but that was the first gift I bought for someone, and it will remain as the biggest mistake of my life.
I never saw any open letter in my life, but somehow i used to think that open letters are something like articles written in personal diary , but now as i know quite a lot about different things know open letters are sort of last thing we want to say about some topic and then completely stop. It is like the last thing you want to say in our break up day meeting , those harsh may be extra emotional words knowing that probably we will never face each other. i heard about the break up stories from my friends and i think i know more about break up dates than any one in this world. My friends are really good story tellers.

And when every bird finds their home back,
no river returns,
some of them dies on the way , never meeting anyone.
they are no more river
just carrying tears of millenium.
