In his science fiction novel Nemesis, Isaac Asimov describes a female character as possessing the "unloveable virtues": Serious, Practical, Responsible, Dutiful.
When I googled the concept, I found this: "Stan Asimov used to say that his brother Isaac had "all the unlovable virtues". Then, while describing a character in Nemesis, Isaac wrote "she possesses what someone once described to me as all the unlovable virtues"."
