Imagine a non-pandemic environment where you could go to a buddy’s house and work. Or for many people, their closest relationships are with their spouse and family. You no longer have to be separate from them for most of your waking hours. Work picks your “friends” for you and in many cases you won’t get along. It seems like you were lucky to be in a good situation.
I think they meant working at a non-colleagues house.
At least, that's what I plan to do when it's possible, every now and then.
I think the change of pace would be nice, back at university I'd do the same with people not on my course.
Being genuinely fond of each other makes time go faster.
Of course, I'd also want to work outside of the office, with my colleagues too. A change of environment every now and then can't hurt.
Pre-pandemic I used to occasionally do this with my coworkers and my boss, it was nice. Of course now all my coworkers and many people I knew have left the city and moved out of state, so this won't be possible again.
