What Can We Do with This Person to Make Them Less Spoiled?
Your mother getting you food when you’re ill is a kind act, not one deserving of venom. And even if the food isn’t to your taste, it’s still nourishing and helpful. Exaggerating how awful the situation makes you look unappreciative and difficult to please.
This is the definition of entitlement. People complain about things that are completely fine only because they’re used to getting whatever they want. If the food is that unpalatable to them, just get takeout instead. You’re overworking your mother as it is.
