Feather

See that feather in the sky?
Wind fanned the filaments
of a once mere vapor trail.

This was actually a few weeks ago, but I never got around to writing anything down about the sight until just before political philosophy today. I'm pretty sure that this isn't much like the poem I had in my head on the very day, but from what I remember, that one was just too awkward (jet-steam vapor trails? even saying that in my head is painful), so I suspect that this one is at least slightly better.
