but you're lonely now that 
everyone's forgotten about you?
aber jetzt, da alle dich
vergessen haben, bist du einsam?!
¿te sientes solo ahora 
que todos te olvidaron?
¿te sientes solo ahora 
que todos te han olvidado?
tu te sens seul
une fois qu’on t’oublie ?
ma adesso che tutti si sono dimenticati di te,
 ti senti solo?
mas agora está triste que 
todos esqueceram de você?
а теперь тебе одиноко
от того, что все тебя забыли?
