the tragedy of time

The Tragedy of the Constance of Time: You Can't Change the Past

On and on, never ending,
Straight line, never bending,
Only forward, no reverse,
Not a blessing, but a curse.

'Cause in this life there's no re-try.
Full steam ahead until you die.
You can't take back the things you've done,
Just run the race until you've won.

Time can't be paused nor be rewound.
It doesn't even once slow down. 
With every second time does burn,
It's past the point of no return.

Oh Time! It's such a tragedy!
For in this life they'll always be
Mistakes, regrets, things from the past
We can't take back--time moves too fast.

Time's unable to forgive;
Oh, what a cruel, hard way to live,
Because of one depressing fact:
Because of time, you can't go back.
