I'm not talking to habitual maskers here - I know you mask all the time anyway. But if you don't mask any other time of year, this is the moment - the next 45 days are the time to mask up in public spaces. Yes, I know it is awkward when other people aren't doing it, but the pain and suffering, and long term health consequences you are going to spare yourself and your family, the better holidays you are going to have, the higher chance that you won't harm a medically vulnerable or elderly family member, are worth it, no?
Honestly, given an unending, immune damaging pandemic, the only sensible strategy would be to to offer OPTIONAL work from home and online school from Thanksgiving to January 15, allowing families that CAN protect themselves to stay home, and those who can't to have much smaller classes with less exposure, and obviously good air filtration and masking.
We aren't going to do anything so sensible, and now we're all fucked by that. But if you can mask, if you can get your kids to mask, do it now. So you get to enjoy your life.
