My mom floated the idea of having everyone "quarantine" for 3 weeks pre-Thanksgiving, so that we could have an indoor sit-down meal. Unfortunately, that's not really possible, because a) my dad and stepmom probably wouldn't agree to it (stepmom thinks the virus is overblown / "just like the flu"; they've been "careful" except for their "trusted circle of friends" who they see in-person for indoor dinners...), b) I wouldn't really trust everyone to have the same definition of "quarantine," and c) my sister wouldn't want to come anyway, because she'd rather take this as an excuse to avoid the big family gatherings.
Right now we're bubbled with my husband's parents, who we basically trust to actually be careful. They're unfortunately still going to grocery stores, which we hope we can talk them out of, but otherwise are on a similar risk level to us. Tentative plan for Thanksgiving is to have a meal with them and some kind of Zoom thing with his extended family, and then do something outdoors with my family the day after. We usually go to a local Christmas tree farm the day after Thanksgiving, so I'd ideally like to do that + masks + distancing.
But: cases are at their highest point ever now, and likely to get worse in the next few weeks. It may be that our risk tolerance goes down too far for even those activities by then. We'll see.
I'm hopeful that once deaths start skyrocketing, people will collectively notice, freak out, and course correct. But everyone may just be too tired of quarantine even then.
