I was walking down a flight of stairs,
and an old woman was walking
below me, carefully, one-step-at-a-time,
arm-in-arm with a younger woman,
dark-haired and slim.
They were talking in low voices,
and I only saw them from behind.
I assumed the girl was leading,
helping the old woman down.
But when they reached the landing
and turned to leave, I saw
that I was wrong, as I often am.
The slim young woman was blind.
