Costing Nothing, Where Sales Tax is Almost 10%

(In response to Jean Young Smith's "Costing Nothing.")

There are times, too, when the moon
          is shrouded in the light and smog
and the buzz and whir of traffic
          and urban hubbub
puff into my open window, like exhaust
          and cannabis, bringing me
great peace. Falling to sleep
          comfortably,
I am thankful, too, for these things
          that cost nothing.
