That's it, all done, I'm vanished now,
All I was has been and gone.
No more time will life allow,
Of further days there are now none.

I couldn't be sure before this point,
Just how long I might well live.
How many days life did appoint,
The span it would me give.

And I lived my life no end in sight,
Each day a new extension.
Enjoyed for their moments of delight,
Ever thrilled at my retention.

But I knew that someday all would end,
My leaving date announced.
The landlord for me insistent send,
My tenure due renounced.

Before I knew it, that time was here.
For this foster child of fate.
The moment I would disappear
Prepare for that fatal date

So here I am, all family weeping,
Clearly sad that I've departed.
Vigil for me tender keeping,
And the mourning from here started.

But this is what life's all about,
Brief period in the sun.
A world me with and then without.
My life started, ended, done.

So that's it, I'm out of terrestrial time,
And though sad, it's how things work
Short sparkle in, spacetime sublime,
Among the quarks, but a quantum quirk.
