The border
of a thing.

Its edge
or hem.

The selvage,
the skirt,

a perimeter's
trim.

The blow
of daylight's

end and
nighttime's

beginning.
A fence

or a rim,
a margin,

a fringe.
And this:

the grim,
stingy

doorstep
where

the lapse
of passage

happens.
That slim

lip of land,
the liminal

verge
that slips

you past
your brink.

Where
and when

you
blink.
