Grey Areas

I don't usually play in them
but they are so interesting.
Neither here nor there.

Just enough for a mention
but not enough for a it to be something
on it's own.

Not a solid
but have just enough substance to go past gaseous.
Suppose it's a liquid then.

Will take the shape of the container
when poured in
will flow away
when poured out.

Shapeless but present
Too much to wave it away,
too little to hold on.

Gripped by the uncertainty
and the mystery.
Will you prove to be a prize worthy of the game?
