Married by Jack Gilbert

I came back from the funeral and crawled
around the apartment, crying hard,
searching for my wife's hair.
For two months got them from the refrigerator,
and off the clothes in the closet.
But after other Japanese women came,
there was no way to be sure which were
hers and I stopped. A year later,
repotting Michiko's avocado, I find
A long black hair tangled in the dirt.
