The exchange happens
every year
every day
every hour.
Maybe the exchange happens
in the dead of night.
In the back ally of
some deserted block in
a busy city.
Mainly, the exchange happens
In broad day.
In flocks of chairs
that pack together in
one busy building.
The exchange is priceless,
so it is sold for free.
No, that's a lie--
You must offer your own--
sooner or later.
There is no due date
no interest
no penalties.
Whether you know it or not
you have taken part in the
exchange
every year
every day
every hour.
