Our embrace lasted too long.
We loved right down to the bone.
I hear the bones grind, I see
our two skeletons.

Now I am waiting
till you leave, till
the clatter of your shoes
is heard no more. Now, silence.

Tonight I am going to sleep alone
on the bedclothes of purity.
Aloneness
is the first hygienic measure.
Aloneness
will enlarge the walls of the room,
I will open the window
and the large, frosty air will enter,
healthy as tragedy.
Human thoughts will enter
and human concerns,
misfortune of others, saintliness of others.
They will converse softly and sternly.

Do not come anymore.
I am an animal
very rarely.

Anna Swirszczynska
