I'm sorry you got sick and wish you a speedy recovery. That said, I am so completely with you on this. The pandemic was the best thing to happen to me. I'm not social, I've eaten all the dinners, fancy and otherwise, I've been to the parties, I've done all the stuff. I'm done. I have no desire to gather with others like that. So now, I just say, "sorry, but I feel a little something coming on." Stops them in their tracks and noone asks any further questions.
