Time’s arrow
you say
drives what we have seen
what we have experienced
what we think will happen.

Like electricity in a battery
power in a pylon line
lightning
the wind in a weather system.

It is why iron
         rusts
dry ice
         moves
                  uphill
why storms
and tsunamis destroy
 and boulders
 
 fall.
 
It is why bones break
why copper greens
why tools wear out,
why people get sick.
 
I ask
Hearts too?
you reply
It is why everything living has to die.
