Is inheritnace the only option

[QueenSvetlana]

So dont use the international_documents method on the Students/International class. Just because its there doesnt mean you need to use it.

I think you mean, don't use it on the Domestic class, right?

Why let domestic see documents, and not use it? Why should domestic even be aware of it? Are you saying inheritance is pointless in this sense? Given that I'm using it because of one attribute.
