Everybody has different wishes.
I, for one, am pretty good friends with my flatmate and it works for me.
My girlfriend barely talks to her flatmates and it works good too.
But she explicitly searched for a flat with people who aren't into the whole "best friends party together" stuff.
And I explicitly asked a friend if he wanted to start sharing a flat with me.
Same with relationships. I do polyamory and many people think I'm crazy and they couldn't live like that, but it works for me.
Or I work from home and people tell me they need an office otherwise they wouldn't get into "work mode", that's why they could never work from home.
Wherever you look it's always the same pattern. People have different ways of living and that's okay.
