Should I consider myself privileged in this respect?
Where else do we find people? Well, we're all older, so we already had friends from other activities -- political involvement, volunteering for arts orgs, our cycling group, etc.
It's nice to have a private office with a couch and windows in it.
On the whole, I am happier working from home for a variety of reasons, but it definitely hasn't been without it's trade-offs.
Some days I work from the park, or work from a bar until I'm buzzed and need to go home.
Also the monetary value of not having to spend money on daily transportation, don't need a huge clothing allowance so you have something decent to wear every day so you don't look like a slob, don't have to waste money on food if your employer doesn't feed you and don't have to waste time preparing meals if you don't want to eat out.
If you need that much socializing time you probably don't have enough work to do, or need a hug.
