Yepppppppp. I always wear a mask indoors. It's not that big a deal, I'd rather protect retail workers or whoever else I interact with.
I made myself a bunch of super cute masks last year too.
For the most part yes, but it's starting to feel a little arbitrary in some places. Wearing a mask to enter a cinema and buy a coffee and some popcorn before going into the screening and taking the mask off to eat said popcorn and drink said coffee feels downright silly.
