Those people saying that this is not house arrest, I think you’re not following the rules
exercising once a day: took the kids out for 3 hours yesterday, that was my once a day. The MN "1 hour rule" exists only on MN, not in any of the guidelines.
Have more catch up with groups of friends on zoom and others because we can, usually no one is home and we see each other a lot less. In normal times, people have things to do, now we have free evenings to be with each other.
Not spending any money on commute and childcare (and holidays unfortunately), so financial situation improving until we can book the next holidays.
The weather has been gorgeous, so I can even send the kids to do their homework outside.
I don't think people know what an actual house arrest would be. This is not it.
If you want to feel miserable, go for it. No one is stopping you or pretending you are not allowed. We are also allowed to look at things on the bright side. I am even spending more and more of my time planning on the best way to leave the UK and have a better life when it's over. My life's too short to be miserable.
