Everyday thermodynamics

Little by little and day by day
The Universe eats itself away
The rivers flow and starlight wanes
till chaos all alone remains

As gases mix, as nations meet
all order slowly turns to heat
You can't escape the grand decline
- Disorder is the world's last line

So who am I to buck the odd
and taunt disorder-loving God?
It's for this reason, I do confess:
I leave my desk in such a mess.
