Things that are

I see
things that are
things that aren't.

I know
things that are
things that aren't.

You see
things that are
things that are.

You know
things that are
things that are.

You don't see
things that are
things I see.

You don't know
things that are
things I know.

I don't see
things that aren't
things you see.

I don't know
things that aren't
things you know.
