english: If you express your request as a conditional -- "if you could open the window, that would be great" -- even though the content is an imperative, the fact that you're not using the imperative voice means that you're not acting as if you're in a relationship of dominance, where you could presuppose the compliance of the other person.
non_english: Ako svoju molbu izrazite kondicionalom: "Ako biste mogli da otvorite prozor, to bi bilo sjajno", iako je sadržina imperativna, činjenica da ne koristite imperativ znači da se ne ponašate kao da ste u odnosu dominantnosti, u kome bi se mogla pretpostaviti poslušnost vašeg sagovornika.
