" Alice loved in order to make up for her own insufficiencies, she searched in others for qualities she aspired to, respected but lacked. Her emotional needs were like a puzzle incomplete without a segment brought by another but the dimensions of the void altered in response to self-development, the piece which fitted at fifteen would no longer fit at thirty. The gap redrew its contours, and unless the puzzle-person kept up she would be left to divorce or awkwardly force the issue. "

― Alain de Botton , The Romantic Movement: Sex, Shopping, and the Novel
