Resigning such a negative act to the concept of shikata ga nai is something I would urge you to have the courage to resist. No parent should force their child to do such a thing; it has incredibly negative implications for the human psyche regardless of how someone is brought up. Culture is not in fact a virtue but a projection of abuse from parent to child down the generations. I understand there is not much you can do about your position, but at least if you understand this it might help improve your life down the line.
yeah, it's like some novel about Feudal Society. Just have to wait 'till I can make a a crapload of money and show them who is the Boss. I'm really optimistic right now
