Is it normal for parents to force you to pay board?

At least you're becoming responsible. $20/week aint bad when you're 18- if you lived in an apartment you'd be begging to pay $80/month...gotta start sometime.

Awwwwwwww, $20 a week board? Poor little you, so sad, so harsh, what a cruel, cruel world hey? Wait till you get a mortgage

Unless I know what the "massive argument" was about, I can't decide one way or the other. The fact that you said it was almost nothing and you won't go into it makes me wonder if the fight was over something you know you were wrong about.
Perhaps you had a fight because you have been mouthy and taking your mother for granted. Maybe she was angry because you haven't been helpful around the house, yet expect everything done for you, like meals, laundry etc. In response, this may be her way of making you smarten up. If it was something she did wrong and you don't like how it is at home, then get out.
As far as your expenses, at your age you should be paying for them.
BTW, you can save almost $500.00 per year if you stop the gym membership, since you can work out at the university. Also, forget about saving for a car right now and use the money towards living expenses and school. You can get around by (oh horrors!) using the bus. Continue to work part-time to support yourself on your own. Many students have done just that.
You didn't mention who is paying for your tuition. If it is your mother, you need to kiss her feet right now. If it is you, then do what I suggest. If you haven't already and are having problems paying for school, get a school loan and/or grant...many students do that also.
Above all, stay in school as an investment into your future. Good luck.

It's not normal. I hate parents who believe their kids owe them when they are the ones who put you into this fucked up world in the first place and totally against your will. That's why I'll never want to have kids.

somewhat normal, depends on family. but the sister thing isn't normal.

I think your mom is jealous and wants you to learn things the hard way, some parents are like that, either do it and keep it cool with her and try to find a better job or move out, and save yourself the stress, you want to stay with her to save money though and just remind her that when you become successful that you wont really feel the need to help her out that much if she doesnt help you out that much, say "Im an investment" I don't get your sister paying though, thats weird.

Lucky it's so cheap! Quite whining about it, or move out! Things are expensive and obviously your parents are trying to teach you that! Good for them! When I was 18, 22 years ago I had to pay $100 a month to live at home. It was way cheaper than living on my own, and I saved up for lots of stuff! I already had a car that I bought at 16, on MY own! Be thankful that you have parents that love and support you, get over it and be happy! Get a better job if that will help, but quit bitching!

Pay your way, your not a child anymore

Life's a bitch, quit your whining.

You should help your Mum put tight git. Get a part time job and pay your way your an adult now.
You'll find out how much it costs if you leave home. Your Mum should kick your ass out some times tough love is better.

18 year old shameless Ungreatfull child

You aren't being "forced", you are free to leave. If you choose to, let me know, $80 a month sounds like a good deal!

Lucky you. As soon as I was 16 I had to pay 50 a week in rent as well as my sister. I was also going to school and working my ass off. When I turned 18 I payed 75 a week. I was paying a car payment rent and a cell phone plus car insurance and my mom and step dad would have kicked me out in a second if I didn't pay. Such is life. It made me have a better appreciation for money and how life is.

$20 a week is sufficient. That barely scratches the surface of the expenses your parents have with you living at home. The point is not the amount of money, which is moot-- don't you see? This is all about teaching you responsibility. This is just a small taste of the real world. $20 a week is not bad.

Your sister paying $10/week is not unfair either. A parent would not ask for the money unless the child has a job.

This is all showing you that a portion of the check and your income needs to go to responsibilties first and foremost. I see absolutely nothing wrong with your parents' method. In fact, I recommend same for all teens and young adults still living at home suckling the homefront. If you don't start somewhere, you'll end up nowhere.

Hell with it,your 18 and you are legally an adult and have your own income.You don't have to pay shit to them. (BTW only 120 dollars a week? Do you collect carts at Walmart or something?? Get a better job like work at grocery store as a bagger.They get like $200 a week!)

I had to pay the same amount. Although making your sister pay too at 16, is a little harsh.

But if you're going to Uni, you'd be living on campus or near it? Or would you still live with your parents?

Because if it's the former, it'll only be a short while before you go so you won't have to pay board for a long time.

so you damn well should! you are using THEIR electricity and THEIR water and eating THEIR food. you need to learn to live within your means and show some responsibility and if you dont want to live with your parents rules then move out of THEIR house. what is wrong with you stupid kids nowadays!! i dont want to to do this and i dont want to do that!! for fuck sake!! you punks are driving me crazy!!
