How many people do you think will perish
while you drone on and on about trivial matters?
كم شخصًا سيموت في رأيك وأنت تواصل
الثّرثرة بلا توقّف حول أمور تافهة؟
Weißt du eigentlich, wie viele Menschen
in diesem Moment sterben,
Mientras sigues obsesionándote
y quejándote por ridiculeces,
Mientras estás aquí haciéndome
perder el tiempo con tus tonterías,
Pendant que tu restes planté là
à répéter tes inepties,
क्या लगता है कितने लोग ख़त्म हो जाएँगे
Hai idea di quante persone stanno morendo
Quantas pessoas você acha que vão morrer 
enquanto você fica com essas bobagens?
Как думаешь, сколько человек погибло за то
время, что ты упирался и говорил глупости?
