yo I had to go out to buy groceries and snacks so I tied a scarf around my mouth and nose. Idk if it does anything to protect me, but it does help protect the people around me from my germs, and like I felt like a shady lady going into the marketplace and all the middle aged people shopping were looking at me like I was, so I just started singing to the music playing in the store really loud as I shopped so people would know I’m relaxed and not looking to be a crook and people started smiling instead and like a few people sang with me. overall I wouldn’t do it all that often because the risk is too high but you know, if I had to, that was pretty ok
