Personally I don't miss working from the office at all. Working remotely is better in every way when it comes to doing actual work.

What I do miss though, is hanging out with my colleagues. It's nice to go for a coffee break or lunch break with a co-worker and just chat about (mostly non-work) stuff. We can organise socials etc. but it's not the same.

I do have my own friends and family that I hang out with anyway, so it's not really a problem for me.
