I want to write "good evening" all the time, colleagues ? Please tell me how weak your immune system is. My husband is sick, and I am not. We try not to be in the same room, but it's still suspicious that it hasn't affected me yet. Ugh. Now my husband thinks he has coronavirus. And I think if so, I would get sick quickly too. Have you encountered colds and flu from close relatives? Did your immune system hold up?
