Crumbs

Large crumbs fall from my plate all day long:
a trip downtown to bring her the potassium she forgot to take with breakfast,
four hours at my mother-in-law's, typing a letter,
a traffic jam on Central Park West
but when, at the end of my day, together we walk through the front door,
I find that what is left on my plate is yet sweet substance,
undiminished.
