As I was leaving my underground parkade and walking toward the building entrance, a women approached at the same time. She was carrying a whole bunch of snowboarding gear. She was mask-less, while I was wearing one (as I do EVERYWHERE). I held the door open for her for several minutes while she struggled to get all her gear in and she thanked me profusely as her face basically grazed my own. In hindsight, I wish I'd just stood back and said, "You go ahead" and let her deal with the gear all alone. After all, that's what you're doing to immunocompromised, at-risk, marginalized folks when you don't wear a mask.
