YANBU because you clearly had a great time. But everyone's experience was different.
I missed my partner, and my wider family; but it spurred me on to make big, useful changes in my life.
I enjoyed the freedom of commuting as a key worker, but not a medical one, so no dealing with Covid patients: I can't begin to imagine what that was like.
I enjoyed extending my commute to occasionally check on aging parents in their garden. Though I worried about them, a lot. (Always within the law/guidelines. I forgot what all the rules were at various points.)
I got to pop into lots of metro/local supermarkets on my commute, and found buying anything - including loo roll and pasta - easy.
I'm an unsociable cow, and just doing loads of online exercise workouts when not at work was amazing. I rinsed Netflix. I think I completed Amazon Prime.
If it happened to me now, with a young family, not living in a city and with a job to physically go to; I would be at the end of my tether with 36 hours. And I would not be nostalgic or grateful for that time. Hats off to anyone who struggled.
