I think a lot of people who answer yes are probably coming at this from a place of never getting a moments peace.
I have always lived alone, since beginning my adult life anyway, and it’s pretty relentless. Financially it’s more expensive, if something breaks, you have to fix it yourself or pay someone to fix it or replace it, bills can’t be split.
Beyond that though, it’s just lonely. Lonely evenings, nights, weekends, knowing there’s a million people you don’t matter to.
