My team has two people including me. She and I are always together and we've been literally the best team ever. But she got a flu 3 days ago, and kept coughing right next to me and she never covered her mouth or wore her mask cuz we were just two of us. I asked her to wear her mask on but she rejected for being uncomfortable. And now I'm positive 🙁 I don't wanna blame her but she really needs her masks. What can I tell her?
