Heh, I actually get those sometimes. I'm disabled, so the only real barrier to complete freedom is family, and I can sneak in a few days a year where I'm alone all day, and sometimes over night.
For real, the only thing I'd do that I can't do when everyone is home is crank the fuck out of the music. My wife gets migraines easy, and my kid seems to be following suit unfortunately. So really turning it up until I can feel the bass in my guts is a rare treat.
But you can only do that for so long before the ears get tired. So the rest of the time would likely be reading without interruptions.
I'm pretty fucking easy to please lol.
I sometimes house sit for my best friend, and that's essentially what I do there, just not that loud with the music because the pets don't like it past a certain point.
Sometimes I'll pop in a movie that isn't to the liking of the family instead of music, and enjoy the more immersive sound. Which, I could also watch things they don't enjoy as much with the sound up, but why not have both factors my way?
Mind you, I can do those things with everyone home, but it takes planning and I'll still have interruptions. But doing them always has the risk of causing my wife hours or days of pain and misery, so it's something I prefer to just wait for. Kinda makes it more enjoyable tbh.
