You have your age as 22-25. Are you from a country where parents still scold their adult children? It sounds like your parents own a rental house, and you are one of the renters. Can’t you move somewhere else?

I mean I guess it depends on if your age range on here is correct. If you are an adult living in your parents house, that is your choice, and if you have an issue with their choices, you can move out. Common decency is to not be absurdly loud when you live with other people, but even if you feel your parents have unreasonable expectations, you are, again, an adult in their house. They can do whatever they want, and you need to abide by their rules or move out.
That being SAID- if you lied about your age on here and are underage, that is a different story. You have no choice but to stay, and they should be a bit more sympathetic. But at the end of the day, it is still their house, they paid for it, and they get to say who does or does not stay there (within reason).

It is their house and their rules until you move out on your own. I can understand your need for privacy and the rest. Can you figure out a solution that your parents could accept? Think. Good luck.

So to you all the kids all across the land
There's no need to argue
Parents just don't understand

How does your sister feel about losing her room ? Are your parents renting the rooms ? Perhaps this is a financial boost that’s needed right now ? If so, maybe being quieter is a small price to pay ?
