My parents have a lot of really strict rules, like the ones you listed. But those are more strict I think, and probably the result of them having so many kids. Like I share a room with my younger siblings, so I have to go to bed at the same time as them so I don't wake them up.
The only strange rule I can think of is me and my siblings never being allowed to touch the TV remote. We got almost no screen time anyway, so I hardly noticed honestly. But it started because one of my toddler brothers went through a phase where they liked to rip off the buttons on the remote and chew on them. And then my parents just liked us never touching/losing/moving the remote, so we have just always known we can't touch it 😂 We have to ask permission to watch TV, and they scroll through the channels and and we can ask to watch something if we see something we like. At which point it becomes a group decision because it has for sure drawn the attention of several siblings and they now want to watch something, too.
