I do enjoy the flexibility of being able to occasionally work from home. But I miss the bustling office culture, going out to lunch with coworkers, forming friendships with people from the office who don't necessarily work in the same department/team.
Most days, I go into town and work from a WeWork (because it's nice to have a daily change of scenery), but 95% of the time, I'm the only person there (in an office with nine desks). Before the pandemic there were 80~100 people in our office.
Sigh...
