"E kelepona i kou hoa."

Translation: Call your friend.

[CATipton]

Didn't another example translate this command form as "should"? That is, could this also mean "You should call your friend."?

[DABurnside]

Friend = hoaloha, hoaaloha; hoa, and more.

[MarkOlsonB]

I thought friend was "hoaloha"

[TehillaTemima]

I saw this and I thought that it was saying "the phone is your friend"

[villajidiot]

So, later we learn that kou is for relationships that are inalienable, ancestral, or surrounding; and that kāu is for relationships that are chosen, optional, or descendent. If we choose our spouses and children, surely we also choose our friends? So why isn't it E kelepona i kāu hoa?
