A Glass Window Is A Glass Window

A few dozen attempts—
bumping her orange breast,
battering fragile grey wings,
tapping tiny claws against
the glass sky of our bedroom
window— brought no success.
We stood on the bed, shoved
our faces against the pane,
knocked, waved our arms,
growled like friendly monsters,
turned on and off track lights
to flash warnings overhead.
Only the latter seemed to give
the robin pause, an inkling
that perhaps an entire world
exists beyond that promise
of sky where other beings live,
move as shadows or gods
beyond her realm, laughing,
shaking their giant heads
at such heartbreaking will.
