As to the various symptoms, I had none of the main three, I had what was similar to the most horrific case of norovirus in August, I have never been so ill, my GP told me to get a test......came back positive! None of the three main symptoms whatsoever, just what felt like the worst food poisoning/worst case of norovirus ever, and in boiling hot August! And I live with my DP who is in the extremely clinically vulnerable group due to being steroid dependent long term and having immunosuppressant infusion therapy every eight weeks. Fortunately, no one else caught it due to me being separated from the rest of the family until I was better.
Regarding bubbles, I had one with my sister who lives on her own but when I found out she was seeing and mixing with loads of other people, I popped that bubble, I just can’t risk it.
OP, you are right but does your mum really get it? I know my dear old mum, since departed, would not have dealt with the lockdowns well and all the restrictions, masks etc etc, yes I would have been cross with her for sure but I wouldn’t believe she had done it on purpose, mind you my mum was 67 when she died, I just thank my lucky stars she didn’t have to live through this pandemic, she would be a complete nightmare!
