he wouldn't have brought his 
jacket here for a button repair.
لما أحضر سترته إلى هنا ليُصلح زرّاً
hätte er den Anzug nicht wegen
eines Knopfes hergebracht.
il ne viendrait pas déposer sa veste
pour un bouton.
non avrebbe portato qui la giacca
per farsi ricucire un bottone.
não teria trazido o terno
só para costurar um botão.
