enigmatic poem

Another poem response to a friend's poem (Nora and Meg are brilliant poets)... this one's very "languagey"... so, we'll see if anyone likes it (or finds something funky about it).

ENIGMA:

This is not where we are.
Are we where "not is this?"
If I were on this, I'd no longer be on that.
Elsewhere is here, but not on this which is there.
Is there a "not is this" existing somewhere?
If this is that and that is this,
There's a there somewhere and a "not is this" elsewhere.

This "are if" elsewhere is "if there's"
here. Certainly uncertainty somewhere?

Are "this, that, there" somewhere? (And) This elsewhere?
Certainly here, not elsewhere, nor there.
