I agree. I fundamentally don't enjoy working in my home. Making the best of it while I can, and my productivity is fine, but it's taxing. I worked for a year and a half remotely a few years prior to the pandemic, and decided I did not enjoy it.

I don't think that makes me resistant to change - I just consider it a change for the worse.

I wonder how much of the pain of today’s impromptu WFH is that there literally isn’t much else available to bring joy and distraction. Am I working more because there isn’t a good separation between work and home or because everything fun is closed?

Even with working more and having a fairly short commute (20-25min ea way), I find I have a lot more time for (solo) hobbies and tinkering. Losing 4 hours a week to commuting and probably another extra 3 to lunch (over quick lunches at home whenever I want) adds up pretty quickly.

I expected to hate WFH, but I like it a surprisingly large amount.

It's totally reasonable that some people prefer a hard separation between home and work, as well as the social aspect of an office. Although, at many work places, I expect the latter is going to be much diminished for a very long time if not forever at many company offices as many employees shift to remote either entirely or for a significant portion of the time.

I would have thought a big part would be people like me who like a good separation between work and home life. When I'm at work I work, when I'm home I don't want to think about work.
