Real togetherness in married couples and indeed in any couple comes from words, not just the words that are spoken – spoken voluntarily – but the words one doesn't keep to oneself – at least not without the intervention of the will.
La verdadera unidad de los matrimonios y aun de las parejas la traen las palabras, más que las palabras dichas—dichas voluntariamente—, las palabras que no se callan—que no se callan sin que nuestra voluntad intervenga—.
