I am fully vaxxed (Moderna jab, twice,) and truly enjoyed 4.5 months of complete, maskless freedom. But now, with Delta, I'm back to masking. Talked to someone DH used to work with, and she said they have had "several" breakthrough cases among the fully vaxxed at the workplace, so there's that.
Biggest problem I have with the mask is that I'm afraid I'll be mistaken for a Democrat. Or, worse, a DUpipo.
