I only spent six months with that girl...
...قضيت ستّة أشهرٍ فقط رفقة تلك الفتاة
Ich habe nur sechs Monate
mit diesem Mädchen verbracht
Solo pasé unos seis meses con ella,
Apenas pasé seis meses con ella,
On n’a passé que quelques mois
ensemble,
Ho passato solo sei mesi
Eu passei só seis meses
 com aquela menina.
Я жил с ней всего полгода...
