I find my wife hath something in her gizzard, that only waits an opportunity of being provoked to bring up; but I will not, for my content-sake, give it.

In Pepys’s domestic idiom, “something in her gizzard” suggests a grievance his wife is holding in reserve—an emotional “lump” she is ready to bring up if given the chance. Pepys frames the situation as a test of self-control: he senses provocation is possible, but chooses restraint “for my content-sake,” prioritizing household peace and his own comfort over the satisfaction of confrontation. The line captures a recurring dynamic in the Diary: Pepys’s acute observation of interpersonal tensions, his tendency to manage conflict strategically, and the gendered, bodily metaphors common in 17th‑century English for suppressed resentment or anger.
