Sissy obeyed. Her rage at being made ridiculous, her sense of outrage that a perfectionist like herself should suffer punishment, added to her knowledge of the flight of time on school mornings, strangled her into dumbness. But she clasped the paper in her breast as a drowning man might a spar from the wreck. At least Number 4 was intact. She had been mercifully spared the fracture of this one of her self-made commandments.
She was standing with her nose pressed firmly against the green wall-paper, her back laid open as by a surgical operation, and a towel, which her aunt had forced into the aperture for drying purposes, dangling down behind, when Kate, passing the door on her way to breakfast, glanced in.
Her sputtering, quickly stifled screech of laughter sent Sissy spinning about as a bull does when the banderilla is planted in his quivering flesh. She looked at the doorway; it was empty, but she heard scurrying footsteps without. Kate was on her way to tell the others.
She looked at Aunt Anne. That severe lady had dropped her book and, seized by the contagion, was shaking with silent laughter.
Not a word did Sissy say. Her expression of disgust,—disgust that a grown-up should be so silly as to see something funny in absolutely nothing; disgust that her aunt should so weaken the effect of her own discipline,—reinforced by the green smudge on her nose, rubbed off the wall-paper, finished Miss Madigan. The lady no longer attempted to conceal the disgraceful fact that she was laughing. She gave an audible gurgle, and began to wipe the tears of enjoyment from her eyes.
In that moment the iron entered into Sissy Madigan's soul. She turned again to the wall, and taking a pin which had fastened the bow of ribbon at her throat, she pricked slowly but relentlessly in the loose wall-paper this legend:
AUNT ANNE—PIG
After which she felt relieved, and, the five minutes being up, left the room with such uncompromising hauteur, still splashed with green on the nose, still split open down the back, with the towel's fringe dangling in dignity behind, that her aunt again exploded.
"Left the room with such uncompromising hauteur ... that her aunt again exploded"
