We‘re getting that from family members too. Basically letting us know that we cannot be with them unless we‘re vaccinated. I assume that you have studied the issue and you’re making an informed decision. Tell them that. You don‘t have to argue with them but simply ask them to respect your decision. Call and let them talk. Say, „I‘m sorry you’re upset.“. Let them talk some more. Then tell them you love them but you have to go.
Just came back over two weeks ago from a family funeral....57 there for select friends and family. ....traveling in planes......and two family gatherings of close to 20..... People from all over the country as well. No social distancing and only two were masked. Nobody has reported covid nor any other illness.
