i feel like it this week has taught us anything, is that a lot of people were ready to be done with this. We have never also given people a sense of when can these masks come off? And i do think t that's been a problem. If you and i had thought ten years ago, ha will be talking about air circulation and carbon dioxide levels on planes, i wouldn't have believed it. So yes, it's definitely a skill set that we need. But have to do better, especially shince. I have cove at 19. Unfortunately, i'll be in my closet for the foreseeable future.
