When people are hungry, they can go to their neighbours who’ll share the little they’ve got and give them something to eat.
I remember the case of a young woman with severe burns who needed somebody to be with her at the hospital to help her eat and wash. Her mother had other teenage children who needed her so she couldn’t be away from home for the long weeks or even months burn patients have to stay in hospital. But her neighbour had older and more independent children and immediately offered to help when she found out what had happened, even though she didn’t know the mother very well at all.
She stayed with the daughter day and night for four weeks, in fact right up until she died from her horrific injuries, and then went home.
