Behind protected glass

Behind protected glass I sit
A visit
He reminds me of me
My seed
He reminds me of everything I wanted to be
I remember dreaming the day would come
My first born son
Your all grown up now
Did it without me somehow
I sent you letters without one reply
But I understand why
Words wouldn't explain
And I'm sorry for unexplained....pain
Behind protected glass I look at you
I see my truth...in you
It's been some time but you came
I heard you no longer carry my name
Son I wish I could go back in time
Just to change this life of mine
I know no excuses will do
But you deserve to hear the truth
Behind protected glass I stand
My son is a man and I can't extend my hand
Damn!...I know I did things wrong
I wish this was a dream all along
You....remind me of me
You remind me of everything I wanted to be
And now I see...you're all grown up now 
You didn't without me somehow
I see my future, my present...my past
Behind protected glass!
