In the quote from Jodi Picoult's "Handle with Care," the speaker reflects on an internal struggle, describing a metaphorical beast residing within. This creature symbolizes deep-seated emotions that sometimes overwhelm them, pushing them towards inappropriate actions. The imagery of the beast suggests a profound conflict between the heart's true nature and darker impulses.

The speaker's experience emphasizes the complexity of human emotions, portraying how anger and resentment can take control. This conflict not only reveals the challenges of managing one's inner turmoil but also highlights the depth of feelings that can exist within a person, illustrating the battle between authenticity and the darker sides of one's character.
