The illusion of eternity.

We're used to clinging to people from the past, justifying it with years of acquaintance. But "we've known each other for twenty years" isn't an architectural argument; it's everyday reductionism. If the mental resonance has disappeared, holding on to form for form's sake is to violate one's own emotional geometry. Midnight is the best time to acknowledge that some connections have exhausted their evolutionary potential. And that's okay.
