I don't know how old you are, but if you are over 18 you can just move out. When I was young my mom would nag at just about everything I did. Although smoking was probably the thing she nagged most about. I got tired of it and just moved. All of a sudden I could do whatever I wanted whenever I wanted.
The downside was that I moved in with my girlfriend. It turned out to be a nightmare, but that's another story. But at least I could smoke whenever I wanted, turn my stereo up as loud as I wanted and a whole plethora of other things that our parents would not approve of!!!
They might not have the money to move out. My son that is 28 is living with me again. I live in CT and it's hard to get a full time job and if you have a part time job and can land another it's hard to get on the same schedule. My oldest daughter just moved out and she is just skimming it. She's also looking for another job and hasn't been able to land one. I'm still looking for a job myself and haven't been able to. The USA is falling apart and nobody wants to hire full time anymore. They save money this way as they don't have to give you nothing if part time( insurance, retirement) My last job was only giving me 4 hours a week..WTH is 4 hours finally told them to take the job and shove it. But that 4 hours would have paid for my juice but not gas to drive to work..lol
