I don't know who
I don't know who I'll choose.
Não sei quem construiu esta casa.
I don't know who built this house.
Não sei quem pegou minha guitarra.
I don't know who took my guitar.
Não sei quem você procura, mas juro que não está aqui.
I don't know who you're looking for, but I swear they're not here.
— Durante a Tormenta (2018)
Não sei quem é o vilão da história.
I don't know who the villain of the story is.
I don't know who it was.
I don't know who called you yesterday.
I don't know who my mother is.
