when he's that upbeat.
.لا داعي للقلق وهو بهذا التفاؤل
Wir müssen uns wohl
keine Sorgen machen.
Parece que no hace falta preocuparse.
Parece que no tenemos
por qué preocuparnos.
Pas de quoi s’inquiéter,

Sta bene, non hai niente di cui preoccuparti.
Não há preocupação
quando ele está assim, né?
Не переживай, смотри,
какой он радостный.
