In Margaret Atwood's novel "Cat's Eye," the narrator expresses a strong preference for coffee over herbal teas, indicating a dislike for anything perceived as mild or soothing. The phrase "real, vile coffee" suggests a complex relationship with caffeine, as it not only provides energy but also a sense of tension that the narrator seems to relish. This juxtaposition reveals a character who finds a certain joy in discomfort, highlighting the paradox of seeking stimulation while being aware of its potentially negative effects.

The mention of coffee as "Jitter in a cup" underscores the idea that the drink embodies both excitement and anxiety. The narrator's anticipation of becoming "tense" illuminates a deeper exploration of the human experience, where pleasure and discomfort often coexist. Atwood skillfully captures this duality, suggesting that the act of consuming coffee is more than just a choice of beverage; it reflects a desire for intensity in life, even when it comes with its own set of challenges.
