everything contains some silence

Everything contains some
silence. Noise gets
its zest from the
small shark's-tooth-
shaped fragments
of rest angled
in it. An hour
of city holds maybe
a minute of these
remnants of a time
when silence reigned,
compact and dangerous
as a shark. Sometimes
a bit of a tail
or fin can still
be sensed in parks.
