I've had this issue from a slightly different perspective. As I've mentioned before, I moved back in with my parents after a massive medical/financial crisis. I'm mostly back on my feet, but not quite financially secure enough to move back out. Now, in moving back in with my parents, I also moved closer to most of my friends, which means I have the potential for a social life. Every so often I go hang out with my friends. Because of my finances, I tend to be the one drinking water, since that's free, unless somebody buys me food/drinks. That does happen. Since I'm not a heavy drinker, my friends will often treat me to one or two drinks. Also, my kids are old enough for me to leave them in the care of my oldest, and I rarely leave before the little ones go to bed, so I'm not imposing on my parents for child care. I have also occasionally taken off for the weekend. Again, my friends know my finances and have split the cost of gas with me, and I left my kids with a friend so my parents wouldn't have to care for them.
Anyway, my parents are trying to "forbid" me to go out. Uh-huh. I'm a 38 year old woman and I make sure that they don't have to worry about child care. I'm not spending money I don't have. I spend my days doing productive stuff. I'm not partying till all hours of the night and sleeping until noon (7 is the latest I get up). While I don't pay rent, I *do* do all the housework and cooking. This is a huge house, and it's a lot of work, but it's fair, considering. The worst I've ever done in failing to do housework is not realize that the kids' bathroom was out of clean towels because I only go in there a couple times a week to clean it, and I didn't realize they'd used so many of the bathroom towels for the pool.
I'm not sure what they're expecting me to do. It's driving me batty.
