PLS HELP Read the excerpt from “Street Cleaning Day.”

An open space on the street
snapped him out of his thoughts
and back to the wheel.
He sped up a little
and moved close to the curb,
pulling ahead of the space.
Just as he shifted his car
in reverse, a flash
swooped in from behind
and took from Square
what the morning had offered.
