Obviously this is very distressing and a failure of the system. What I'm curious about is that she didn't call her son to ask for help. I wonder how much of that is embarrassment over her situation. Stories of bodies being found weeks after death by neighbours or relatives are all too common, though I've usually assumed it happens mostly to the elderly who have no surviving friends or family.

Also possibly a cynical take but I wonder if her son being there and calling the ambulance on her behalf would have resulted in the situation being taken more seriously.
