Harbouring

Although I almost instinctively felt some resentment that my employer had placed me on probation after my mistake, I soon overcame my feelings of animus towards her and, instead of harbouring a grudge, resolved to treat the entire affair as a necessary learning experience.

Scarce out of sight of Sicily, they set / their sails to sea, and merrily ploughed the main, / with brazen beaks, when Juno, harbouring yet / within her breast the ever-ranking pain, / mused thus: "Must I then from the work refrain, / nor keep this Trojan from the Latin throne, / baffled, forsooth, because the Fates constrain?"

She has been harbouring a great level of resentment all these years.
