Sis would always work 
herself to death for me!
!كانت أختي تعمل جاهدة دائمًا
Sie hat sich für mich
immer halb zu Tode gearbeitet.
Mi hermana trabajaba
hasta la extenuación por mí.
Mi hermana trabajaba
hasta la extenuación por mí.
Elle se tuait au travail
pour subvenir à mes besoins.
Mia sorella si è sempre spaccata la schiena 
lavorando per il mio bene.
Ela sempre se matava 
de trabalhar por mim!
Сестричка всегда убивалась,
чтобы я жил хоть немного лучше!
