In a few years time
this
whatever this is
won't be possible
or we
or one of us
won't want to
or
we won't be able to
or
worst of all
it will no longer be appropriate
so
while the sun still warms our skin
and
while the air is still drawn in
or
exhaled from our lungs
and
while the water still is cooling
let's dive in and swim
until
this isn't possible
whatever this is
