This thread is posted daily, and is intended as a place for more-casual discussion of the coronavirus and questions/updates that may not warrant their own dedicated topics. Tell us about what the situation is like where you live!

Whether it's a personality trait you have, an experience you've been through, or a way that you "come across" to others, or something else entirely, what's something that people commonly misunderstand about you? Why do you think that happens? How do you feel or respond when you're made aware of it?
