Since I’m off work with Covid I’ve reverted to my internal clock of staying up until midnight. And because of covid I tend to sleep 12 hours a night. (Yes, still after 2 months ... it’s a slow recovery and at this point I’m hoping I’m not one of those long haulers who goes on disability). My husband generally goes to bed at 7 and gets up at 4.
This is a foreshadow of when we are both retired, and it works. He gets mornings alone and I get evenings alone and we have about 8 hours together.
And yes, it would bother me to be quarantined together and on the same sleep/wake schedule. I need time alone.
