The big difference is I don't go out to shop as much (which is nice), stay 2 meters away from people in line-ups (which is REALLY nice!), and the rest of my life stays about the same. I work, am too tired to socialize after work, but I found a tiny bit of extra time to exercise almost every day. Yoga and running... and I always run by myself, so that's the same. Yoga replaced bouldering (which I would do mainly by myself anyways). Now I'm on the computer by myself.
The only thing I will miss is the family dinners, although I am an introvert and I find those really emotionally exhausting, as much as I want to be there.
All those social butterflies are just dying, eh? Welcome to reality. Work and no play... Although, if you don't want anymore either, you may just go crazy.
