It's been so peaceful lately, 
we completely forgot!
كانت الأجواء هادئة للغاية لدرجة
أننا نسينا تماماً
Weil es so friedlich war,
haben wir das vergessen.
¡Hubo tanta paz 
últimamente que lo olvidamos!
¡Hubo tanta paz 
últimamente que lo olvidamos!
Depuis le temps
qu’on s’est pas battus…
Era tutto così tranquillo 
che ce la siamo dimenticata!
A paz é tanta que até
 esquecemos dele!
