Adressee Not Found

The postman comes after many days
And hands me a letter
With an address written in my hand and I can see
Long back I had written a letter to myself
On an address where I never lived
And they took it so long to bring it back
Well it was there anyway, after all
Back to its sender who unknown to them
Was the addressee too.
And I could see the stamps of failed attempts of delivery
And a final stamp of “Addressee Not Found”
The letter unfolds and asks me a question:
“Have you found yourself?”
