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