when the petrol tank is empty, but you keep driving

You can stay awake until you collapse
While a building is hollow but stands
You've no reason to go forward but for
Curiosity?
A pain burns yet you must go forward
You choose to live, yet dying is easier
What is in you that makes you go on
Wonder?
Why go on, why tolerate all the hatred?
Yet make it to that feared destination
For what, why pay such a cost?
If you are empty
And have nothing to pay
What is left but the end?
Still going, even on foot.
Live just to give the lack of a clear answer the biggest middle finger there is.
