I think both, for me.
I was home, not going into the office from mid-March 2020 to early June 2020. Then I started going into to work two days a week for four hours per day, and that increased to 3d x 4h in the fall. I have my own office at work, so could go in and stay in my office without interacting with a lot of other people. I was going to restaurants since they opened up here in the summer of 2020, but eating outside until the fall. I credit New York state and Connecticut with Covid guidelines as far as mask mandates for public buildings, so everyone had to wear a mask. I haven’t gone to any movie theaters, even though they’re open now.
When I go out, I shower when I come home (as well as before I go out). I don’t know if that’s overkill, and nobody recommended it, but it’s what I do and maybe it’s helped, maybe not. I don’t wear my street clothes around the house, either.
Nobody that I’m close to got Covid. Nobody that I work with and nobody in my family or any close friends. We’ve all been lucky and we’re all diligent.
I got one shot (Moderna) and I’m getting the second shot this coming Friday.
