Picture a point, then place

the point on a line, imagine it moving along the line.
Let the point be my mother, A, and the line be a hall in an airport.
Let the point traverse the line, the line ABĀ  where B
is the future, a departure gate, too far away to see
though you may name it gate 67B.
Let the line bisect a circle that is the whirl
of departures and arrivals, people and machines, and air currents,
and let her be the point in the center. Then let her move
as a firefly moves, and let her be the light as a firefly is light, on, off, erratic,
erotic, let her be the point of light in the whirl.
