I'm not downvoting, but you're limiting what OP is saying. They never limited themselves to "out for a walk and... social distancing".

I wear a mask outside while walking and social distancing and I'm not virtue signaling. I simply personally find it harder to futz w/ a mask when coming up on people or going inside a building.

Please be a little less reflexive when it comes to this stuff. I'm sure people are "virtue signaling" by wearing masks. But coincidentally they're also limiting the spread of COVID-19. Let's focus on the latter here.
