Or maybe even, as they said quite plainly, "at-risk family members".

Personally I wouldn't wear a mask any more; as others have said I think there comes a time where unless there's a specific heightened risk you have to accept that you either stop at some point or wear one for the rest of your life.

That said, I have immediate family who are extremely immuno-suppressed. I either wear a mask, or every day I increase the risk of killing them. So I wear a mask.

Sometimes the argument is pointless. The "other side" may even agree with you. Yet life often makes a mockery of our choices and forces behaviours upon us.
