" I am who I am.
A coincidence no less unthinkable
than any other.

I could have had different
ancestors, after all.
I could have fluttered
from another nest
or crawled bescaled
from under another tree.

Nature's wardrobe
holds a fair supply of costumes:
spider, seagull, field mouse.
Each fits perfectly right off
and is dutifully worn
into shreds. "

― Wisława Szymborska , Monologue of a Dog
