[A 404 page] is the feeling of a broken relationship.

Gleeson frames the commonplace “404 Not Found” error as an emotional event rather than a technical one. By likening it to “a broken relationship,” the line suggests that users experience a moment of trust rupture: they followed an implied promise (a link, a navigation path, a brand expectation) and arrived at absence. The metaphor highlights how digital experiences carry social and relational expectations—sites are not just information systems but ongoing commitments to be reachable, coherent, and responsive. In design terms, it implies that error pages should acknowledge disappointment, repair trust, and offer a path forward, because the user’s frustration is less about the missing file than about feeling abandoned or misled.
