If life were a book

But if life were a book
One you could predict
Where even before tuning the page
Its content had become known to you

What then? 
What would happen to us after tuning the page?
We need to go back to chapter one
Reread our story from the top
Reviews our choices from back then
Then, and only then
Could we predict the next page,
The next chapter, the ending

But if life were a book
One with a sad ending
One that make children cry
Would we change it?

If so then I need to know why
Why are some sad with their lives
Couldn’t they just change it?
Why are some adamant with staying bad
Can’t they see they’re in the wrong?
I see it's all a matter of perception
Or perhaps I am wrong in every way
Perhaps it is fate but couldn’t it be altered? 

But if life were a book
What genre would yours be
Which character would you be
What awaits in the next page?
