Provisional

I've read the fine print now
the clause they never read aloud.

Not through, but until.
Not anchor, but ballast
for a ship that may yet
choose lighter waters.

I fill the space
between walls
the way light does
useful, unnamed,
gone when the switch is found.

Worse is just
a weather word
until it isn't.
Then it's a door.

I'm learning the shape of temporary.
How it fits like something permanent
until it doesn't need to.
