i agree with your first statement. it could have many literal manifestations.
about the STS / STO comment; It's an interesting reflection on this piece.
i feel that as long as the "visitor" is just looking, seeing.. it could have STO intentions / tendencies because although STO adheres to "non-interference" it does not stay blind to any environment it finds itself in.
but then again, anything could be seen as STS OR STO by anyone, and of course i don't mean whole entities, but micro-interactions.
thanks for the input
