My new windows are transparent,
Free from smudge and tarnish.
I was clear-eyed gazing out,
Reflective peering in.
Two-sided.
Finger prints have been wiped free,
But around the edges there are still ridges,
Evidence of being opened and closed,
Unbroken in their sturdy frames.

But time is no friend to glass.
Winds assail it, birds bounce off at break-neck speed,
Dust accumulates, it becomes opaque.
Missiles assault its permanence,
Shattering the pane into foreboding shards, like a shell.

Some desperate glazes never get replaced,
They invite stone-throwers.
Then the building becomes derelict, untenable.

One stone can break a window,
Or fell a giant.
