Survivor is right. If you're studying, *you* are studying - if they want to enrol into adult ed, they're free to do so...
Are they afraid you'd have too low grades - would the people you work for see those grades and expect someone with 'best grades only'?
After I finished University, nobody asked me what grades I had!! It's just important to finish... (Future employers like to see a photocopy of a diploma!!) Maybe if you wanted to work in a top-notch company that chooses only Top ten Harvard graduates or something..? Are your parents actually hoping for something like that? Would you like to work in a place like that too?
Have you threatened to quit college or made them think you were not going to do your assignments or such? Or did you do any serious breech of trust like illegal drugs or such? If not, do your homework and slowly do some more things independently too...
Other things - be happy with it or be diplomatic and resourceful about it..
They may be happy to cook etc for you now, as you work and study... If you quit work and/or study, they may suddenly expect you to do everything... And it's actually better to be prepared... How about you study a recipe online and just surprise them - or yourself - with a meal? Maybe you can cook supper or lunch, if they normally cook a meal at another time of day?
Explain to them that your wife/husband may expect you to know how to cook too, etc. and that you'd like to learn, and ask to be 'apprentice' and if they can 'teach' you a master dish that you'd like to learn how to cook?
Also maybe find perfect timing just before your mom does something (she probably has a schedule?) and just do it sooner?
Also what if they died? (Of course say you want them to live a long and happy life, but no one knows...?) Would they want you to be unfed/hungry and walk around dirty? Maybe this will help them see some logic?
Though maybe they're just thinking they're showing you their 'love' with this... So the apprentice thing might work well... (Unless they're a world-famous restaurant chef and the recipes are a trade secret?? )
Maybe they also like to be needed... Maybe you could ask for opinion now and then, in things that don't really matter that much to you, or where you really don't know what to do - but only if they are 'adult' things, for any dilemmas that might make them go 'ooh he's a kid' it's maybe better to write into a journal and/or talk to friends/classmates/a counsellor (you probably have a school/college counsellor?)/here/etc?
I think your parents need some hobbies!! Or a charity or volunteering to work with, or some other social contacts or work to do!!
So they can focus their creative energies on something else too!!
Can you inspire them to join something they might find interesting?
It was such a relief when mum joined some organisations and met people and did stuff through volunteering etc!
You can also ask mom to 'teach' you how to do laundry - maybe she has a very complicated system (mine does) and is afraid you'd color her things or do something wrong.. Beware, if you do it well, she may expect you to do the laundry for whole family then! lol!
