!لكنّنا أقسمنا على صناعة صاروخ
Ich habe versprochen, dass wir gemeinsam
eine Rakete bauen und ins Weltall reisen …!
pero nos lo prometimos.
pero nos lo hemos prometido.
je l’ai promis à mes amies.
ci siamo promesse di costruire un razzo
Mas prometemos que
faríamos um foguete!
но мы поклялись построить ракету!
