Reciprocity by Wislawa Szymborska
There are catalogues of catalogues.
There are poems about poems.
There are plays about actors played by actors.
Letters due to letters.
Words used to clarify words.
Brains occupied with studying brains.
There are griefs as infectious as laughter.
Papers emerging from waste papers.
Conditions conditioned by the conditional.
Large rivers with major contributions from small ones.
Forests grown over and above by forests.
Machines designed to make machines.
Dreams that wake us suddenly from dreams.
Health needed for regaining health.
Stairs leading as much up as down.
Glasses for finding glasses.
Inspiration born of expiration.
And even if only from time to time
hatred of hatred.
All in all,
ignorance of ignorance
and hands employed to wash hands.
