But I was happier than anyone else in the world.
لكن كنتُ أسعد من أيّ شخص آخر في العالم
aber ich war glücklicher
als jede andere Frau.
pero fui más feliz que nadie.
pero he sido más feliz que nadie.
mais j’ai été plus heureuse
que n’importe qui.
ma sono stata più felice di chiunque altro.
Mas fui mais feliz que
qualquer outra pessoa.
но я… стала счастливее всех на свете.
