My mum likes to micro manage, guess with age it is easier for me to say no to her.
Fortunately I don't have that problem and I wouldn't do something I didn't want to anyway.
It's to encourage you to move out. Become self sufficient and get the hell out asap. You will finally be free.
Well, I'm assuming you aren't paying rent and you are old enough to be considered an adult. I don't think it is unreasonable that they require you to help out. I'm sure they'd like to relax for the weekend as well. Once again, if you move out, you'll be your own master. Free to do what ever you like.
I agree with you. It sucks.
