I think Hermione would be a teacher. Ron, IDK maybe an average job in a store или something. I see Harry as an inspecter, I have NO idea why..LOL don't ask.
I can see Hermione being an Activist или a Librarian. Ron I can see being a stand up comedian, или working in a retail store that sells * sweaters-kidding. Harry, I can see him being a therapist или working with orphans who have problems.
I think Hermione would be a teacher или librarian, Ron would be a janitor или a postal worker (something mundane and weird like that - not that I have anything against those professions!) and Harry would be a school counselor, social worker или a police officer! ;) LOL
I didn't give it ANY thought I just сказал(-а) first things that came to mind but Librarian или Teacher for Hermione Is such a good IDEA!!! I suppose we all think Ron wouldn't be as sucsessful and Harry Something Social или important
