I personally don't think she was sick last week at all. I think she was keeping a low profile so that she could drive in and out of Brighton to take pics, and then used 'not feeling well' as a reason for her long silences. I think it was all made up.
I supppose she's so thick that she thinks she's not doing any harm because the streets are empty anyway therefore no chance of spreading anything. What she forgets is that one of the whole points of staying home and not driving around is to lessen the risk of road traffic accidents, thereby pressuring the emergency services even more. When my husband and I had covid and I had to phone an ambulance for him because he couldn't breathe, the ambulance took an hour and twenty minutes to arrive, while I sat with my husband watching him gasping like a fish. And that wasn't even during a lockdown. It probably took so long because ambulances were in short supply due to other people (like Lorna) behaving llike idiots. Does she think ambulances and emergency services are in bottomless supply?
