Why the stars have to be so faraway?? Why my star is so untouchible?? I only want to sent him a letter with best greetings...but would i be realized wrong??…

The stars are so far away, because the universe has developed in such a way since the Bib Bang, or because it has been created that way - depending on how you think of it. But then again, if the stars were closer, they would burn us... So, that's why the stars have to be untouchable.

Well then, if your "star" is a human being, I can't see any reason why you couldn't send him greetings in a letter. Of course it is impossible to say how he would react to your message, but at least I would be delighted to get greetings from somebody - even from a person I do not personally know. The only way to find out his reaction is to try and send him the letter you are planning.

Of course he may remain untouchable to you anyway. But even if you don't get a personal contact to your star, remember that it is not wrong to reach for the stars! As it is so beautifully said in the song "The impossible dream":

To dream the impossible dream
To fight the unbeatable foe
To bear with unbearable sorrow
To run where the brave dare not go
To right the unrightable wrong
To love pure and chaste from afar
To try when your arms are too weary
To reach the unreachable star

This is my quest
To follow that star
No matter how hopeless
No matter how far

To fight for the right
Without question or pause
To be willing to march into Hell
For a heavenly cause

And I know if I'll only be true
To this glorious quest
That my heart will lie peaceful and calm
When I'm laid to my rest

And the world will be better for this
That one man, scorned and covered with scars
Still strove with his last ounce of courage
To reach the unreachable star
