Then, on one of my “swing-bys”, Mum didn’t smile when I tapped on her window. She looked dreadful and her speech was slurred. It seemed as though she was having another stroke, but after she’d arrived at hospital she tested positive for Covid. For six days, I couldn’t see her. Then came the call that I could. On Covid wards, that usually only means one thing – that the patient is not expected to recover.
