I don't consider myself locked up. I miss in person game nights the most, i miss dinner with friends (in a private home or restaurant) somewhat.
We do gamenights online using videochat and products like roll20 and boardgame arena. It's not super awesome but it works for us for now.
I leave the house, go on walks go shopping etc. But I take very reasonable precautions. I shop during low traffic times, get up early and hit the grocery store before work, I order food for pickup and wait outside for it. During the more temperate months we'd set up a few tables in the backyard and have friends over for meals, each 'pod' got their own table nicely distanced, we were probably a little louder than most dinner parties but it was nice just to have them around.
For a friends birthday we wanted to go see spiderman, we rented a theater (it was actually not especially expensive) invited about 20 people who we knew were supervaxxed and responsible enough not to come if they though they might be exposed and had a grand, masked and distanced, time.
I'm just trying to be responsible, I know several people that are immunocompromised and they can't even do half that stuff. I'm trying to be responsible so that they can. When some asshole declares that 'covid is over' I just realize how fucking narcissistic they are.
