Bygones' Comeuppance

I love
stealing up behind them one
by one
savoring the glance of sun on bumpers
I thought I'd seen the last of
their license plates and stickers
to see what they belong to
where they're from
making monkey-faces at the children
in the back window as I creep up
on the drivers
who went by
until we pull up level and pass
and I nod them howdy from the car
that stopped
just to see if they'll
next time they come
