Nod's mum has been sent home from hospital. She is bonkers and therefore declined the twice daily care package offered to her. "My sons will look after me"., No they won't. "My friends will look after me." All those geriatric octogenarians who are self-isolating? "The vicar will look after me." He is praying for you.
Nod is inclined to let the daft old bat starve.
