For their kids' sake, 
parents can't always come home!
لا يمكن للآباء العودة إلى
!المنزل دائمًا لأجل أطفالهم
Man kann doch nicht immer
heimgehen wegen der Kinder.
Los padres no siempre pueden ir
a casa por sus hijos.
Los padres no siempre pueden ir
a casa por sus hijos.
I genitori non possono correre a casa
ogni due minuti per il bene dei loro figli.
Os pais nem sempre podem voltar
pra casa só por causa das crianças!
Ради детей родители 
не приходят домой вовремя!
