Answer:
The poem "The Grumble Family" mainly discusses the theme of discontentment and being unsatisfied with whatever is being given to man.
Step-by-step explanation:
The poem "The Grumble Family" written by an anonymous writer talks of the discontentment of humans with whatever they have and no matter what is being given to them or provided with, they will still get other issues to grumble about. The Grumble family represents the 'class' of men who are always dissatisfied with their lives, and can never find happiness in the little they have. And if anyone is to mingle with the 'Grumble Family', they will imbibe in them the same mannerism and become like them in no time. This is the effect that a negative aspect of humanity can have on others, even if no one wants to a part of.
