I answered on another thread when you asked me. I said that I’ll keep wearing a mask until we reach herd immunity, or the only people preventing herd immunity are those who refuse to vaccinate. Over half a million Americans have died from COVID and that number would have been much, much less if everybody masked up early. I see it as a very small sacrifice to protect people.
Like @ryanJ said, it doesn’t both me much and it makes others safer/feel better. I similarly don’t wear them outside. I wear them when I am in public places. Now that I’m vaccinated, I can have mask-free family gatherings.
