It reminded me of a poem I read this week in Risking Everything, edited by Roger Housden:
"For The Sake Of Strangers" by Dorianne Laux
No matter what the grief, its weight
we are obliged to carry it.
We rise and gather momentum, the dull strength
that pushes us through crowds.
And then the young boy gives me directions
so avidly. A woman holds the glass door open,
waits patiently for my empty body to pass through.
All day it continues, each kindness
reaching toward another - a stranger
singing to no one as I pass on the path, trees
offering their blossoms, a retarded child
who lifts his almond eyes and smiles.
Somehow they always find me, seem even
to be waiting, determined to keep me
from myself, from the thing that calls me
as it must have once called to them -
this temptation to step off the edge
and fall weightless, away from the world.
