The audacity of some people (let's be real: generally older men) to tell others to smile. Who do they think they are? Rep that long hair \m/
But anyway, I'm fully vaccinated and I've still been wearing a mask when leaving the house, although I've started wearing it on my wrist when on walks, putting it on if I pass someone on the sidewalk. It's mostly a courtesy; other people whom I see usually do the same thing.
I think as restrictions at the offices, stores, restaurants, etc. open up I'll generally stop wearing one. I will, however, put one on if I'm sick and going out in public for whatever reason. Too many times have I been guilty of not taking a sick day when I probably should.
