I think you should pay something towards rent and towards keeping the fridge stoked as well… pay your own way… but not so much as to get into debt… also since u r staying at home, i dont see how u would need a lot of money for “stuff”… i understand gas…
the reason i say this is that it will teach u to budget and live within ur means… also, u need to realise that ur parents are getting old and need to save up as much as they can for retirement so help them out as much as you can while you can… as once u r married, u will have ur own responsibilities which might hinder u!!
just my :twocents:
