> I don't think a single one of my friendships involve a common enemy, beyond both of us being allied against boredom. Similar here. The "common enemy" in my friendships typically refers to something impersonal, such as the universe or sickness or falsehood; but often something much less dramatic, such as boredom or being alone. Maybe this is just a way to reuse the ancient brain circuits that evolved to create coalitions against human enemies. But the evolutionary purpose of something, and how I use it in my everyday life, those are often two different things. Maybe most people only use those ancient brain circuits the old way, dunno. That sounds horrible, but I guess it could explain some horrible parts of reality. But it's definitely not the only way.
