Since the Dane County mandate expired at the beginning of the month, I've stopped wearing a mask in common areas of my apartment building and other public indoor spaces where I'm just passing through (such as when I'm taking the trash to the chute or walking to/from my car in the basement garage). I'm continuing to wear them in grocery stores and other places with either a lot of people and/or I'm going to be spending an extended period of time.
I'm fully vaccinated, but people don't know that by looking at me, so I mainly do it as a courtesy and on the slight, but nonzero chance that transmission is possible from a vaccinated, asymptomatic individual.
