Even though I'm vaccinated, knowing most are not yet makes me hesitant so as an at-risk person I'll keep it on in indoor public spaces.
I think it'll also give others who are still waiting to be vaccinated some peace of mind - they've no way of knowing whether I'm vaccinated or infected and life is hard enough.
Exactly. Even if I was vaccinated, how would I prove it? And would I want to spend time proving I'm vaccinated to anybody who cares to challenge me? It's easier to just wear a mask.
