In Chapter 4, Minny thoroughly enjoys a freshly-picked peach in Celia's kitchen while cooking down some butter for the fried okra she is making for dinner. The smells and sensations of the kitchen are so overwhelmingly pleasant that Minny does not even notice Johnny arriving home. She escapes into the guest bathroom, which is much less enjoyable than the kitchen:
But what with the juice running down my hand and me nearabout drunk on the butter smell, I am lost in a peach-peeling reverie. I don’t even notice the blue truck pull in. [...] I snap into decision—the guest bathroom! I slip in and keep the door cracked. I crouch up on the toilet seat so he can’t see my feet under the door. It’s dark in here and hot. I feel like my head’s on fire. Sweat drips off my chin and splats on the floor. I feel sick by the thick smell of gardenia soaps by the sink.
The bathroom is too hot, and Minny "feel[s] like [her] head's on fire." The intoxicating scent of melting butter turns into too-strong hand soap. The quick swap in sensory imagery from kitchen to bathroom helps to show the equally quick transition from "reverie" to fear. First, Minny's total enjoyment of the peach and butter represents the safety and peace she feels with Celia. But the fear, heat, and discomfort in the bathroom represent in turn the fear Minny feels toward Johnny. Thus, the total switch in sensory imagery, while only going from room to room in the same house, shows the range of emotions that Minny feels in that house. Celia's requirement that Minny remain secret means that she feels as much peace in the aromatic kitchen as she does fear in the stuffy bathroom.
Minny and Aibileen attend mass together in Chapter 10. Sitting next to each other during the service, Aibileen tries to convince Minny to participate in Skeeter's book. Though Minny does not want to involve herself with the project, she understands Skeeter and Aibileen's quest for the truth. She describes "truth" using a simile that introduces tactile imagery:
I can’t believe Aibileen wants to tell Miss Skeeter the truth.
Truth.
It feels cool, like water washing over my sticky-hot body. Cooling a heat that’s been burning me up all my life.
Truth, I say inside my head again, just for that feeling.
Minny compares "truth" to "water washing over my sticky-hot body." Through this simile, Minny connects the racism and oppression in Mississippi with its hot, humid climate. Just as Minny sweats through the muggy southern weather—though this scene takes place in December, it is still hot outside—so too does she struggle through the cruelty and rudeness of White bosses. Minny often complains in the novel about the heat and how she sweats worse than anyone else; this is consistent with Minny's constant desire for truth and fairness, often to her own detriment. In contrast, "truth," the real stories of the experience of Black housekeepers, feels like cool water, in contrast to this hot oppression. The pleasurable, cleansing experience of the truth will prove to be so enticing to Minny that it will eventually cause her to agree to participate in the book.
After Stuart breaks up with Skeeter at a dinner at his family's mansion, Skeeter feels hurt and confused. In Chapter 21, she describes these feelings using tactile imagery tied to the family's new air conditioner:
[My parents] do not know Stuart broke up with me after the Whitworth supper. Or the relief I long for from this machine. That every minute I feel so hot, so goddamn singed and hurt, I think I might catch on fire. [...]
On tiptoe, I turn out all the lamps, the television, every electricity sucker downstairs save the refrigerator. I stand in front of the window and unbutton my blouse. Carefully, I turn the dial to “3”. Because I long to feel nothing. I want to be frozen inside. I want the icy cold to blow directly on my heart. The power blows out in about three seconds.
First, Skeeter describes her feelings as heat. She feels "singed and hurt," as if her relationship with Stuart was a fire that burned her. Because of this, Skeeter craves the cool air from the air conditioner. To the characters in the novel, this is a newfangled and unfamiliar device, installed to aid Charlotte's health in the wake of her cancer diagnosis. Skeeter craves the cool air because she wants to be "frozen inside." If heat and fire represented overwhelming emotions, Skeeter longs to feel no emotions, to be frozen cold. But this is only a fleeting balm for Skeeter's emotions, as the power blows out immediately.
Blistering heat is a common image in the novel. Typically, it is used to represent the omnipresent effects of racism and oppression, like hot, sticky hair draped over the entire city. Here, though, heat as imagery applies more specifically to Skeeter's emotions.
Near the end of the book, late in Chapter 34, Elizabeth fires Aibileen, supposedly for stealing silver. Mae Mobley, who is sick with fever, does not understand why Aibileen, her only mother figure, has to leave. Aibileen describes her tearful goodbye with Mae Mobley using hyperbolic figurative language:
“Why? Why don’t you want to see me anymore? Are you going to take care of another little girl?” [...] Law, I feel like my heart’s gone bleed to death.
I take her face in my hands, feeling the scary heat coming off her cheeks. “No, baby, that’s not the reason. I don’t want a leave you, but…” How do I put this? I can’t tell her I’m fired, I don’t want her to blame her mama and make it worse between em. “It’s time for me to retire. You my last little girl [...]."
Aibileen's reaction to Mae's sadness is full of powerful pathos: "I feel like my heart's gone bleed to death." Aibileen and Mae's relationship formed the first few sentences of the book, and now the moving pain of their separation forms the final few sentences. Aibileen's hyperbolic statement about her heart bleeding "to death" recalls Christian imagery, particularly of the Virgin Mary, who is often depicted with her heart pierced by seven swords. The bleeding heart is often a symbol of great sadness, as it is for Aibileen here.
The entire scene is also very physical, making use of tactile imagery. Aibileen feels her pain as a physical wound in her heart. She then feels Mae's face, with its "scary heat" from her fever. Their final interaction takes place in this pose, Aibileen holding Mae's face. This interaction frames their relationship as something innate to them, something held in their body.
