Co-presence can be one-sided without reciprocity. [contrarian]
The prey and its predator lurking in the shadows are co-present even if the former is not yet aware of this (or even if the prey cannot yet see the predator). For there to be co-presence, all that is necessary is that one of the terms involved should be included in at least one field in range of the other. There are paradoxical forms of unilateral co-presence in which entity A can act upon or be affected by entity B, while entity B is not in a reciprocal position. Here, the prefix “co-” indicates no reciprocity in the relationship but simply a common inclusion.
