I can't believe I took so long 
to notice I forgot something.
لا أصدِّق أنّني استغرقتُ وقتاً طويلاً لألاحظ أنّني نسيتُ شيئاً
Unfassbar, dass ich erst jetzt gemerkt habe,
dass ich was vergessen habe.
Tardé mucho en darme cuenta 
de que se me quedó algo.
Tardé mucho en darme cuenta
de que se me olvidó algo.
J’ai oublié quelque chose
et je m’en souviens que maintenant…
Incredibile, non so come ho fatto 
ad accorgermi solo ora di essermene dimenticata.
Não acredito que demorei tanto 
 para notar que esqueci de algo.
