Read the excerpt from "The Open Window." "Her great tragedy happened just three years ago,” said the child; "that would be since your sister’s time.” "Her tragedy?” asked Framton; somehow in this restful country spot tragedies seemed out of place. "You may wonder why we keep that window wide open on an October afternoon,” said the niece, indicating a large French window that opened on to a lawn. "It is quite warm for the time of the year,” said Framton; "but has that window got anything to do with the tragedy?” "Out through that window, three years ago to a day, her husband and her two young brothers went off for their day’s shooting. They never came back. In crossing the moor to their favourite snipe-shooting ground they were all three engulfed in a treacherous piece of bog. It had been that dreadful wet summer, you know, and places that were safe in other years gave way suddenly without warning. Their bodies were never recovered. That was the dreadful part of it.” Here the child’s voice lost its self-possessed note and became falteringly human. "Poor aunt always thinks that they will come back some day, they and the little brown spaniel that was lost with them, and walk in at that window just as they used to do. That is why the window is kept open every evening till it is quite dusk. Poor dear aunt, she has often told me how they went out, her husband with his white waterproof coat over his arm, and Ronnie, her youngest brother, singing, ‘Bertie, why do you bound?’ as he always did to tease her, because she said it got on her nerves. Do you know, sometimes on still, quiet evenings like this, I almost get a creepy feeling that they will all walk in through that window—” She broke off with a little shudder. It was a relief to Framton when the aunt bustled into the room with a whirl of apologies for being late in making her appearance. "I hope Vera has been amusing you?” she said. "She has been very interesting,” said Framton. "I hope you don’t mind the open window,” said Mrs. Sappleton briskly; "my husband and brothers will be home directly from shooting, and they always come in this way. They’ve been out for snipe in the marshes today, so they’ll make a fine mess over my poor carpets. So like you men-folk, isn’t it?” She rattled on cheerfully about the shooting and the scarcity of birds, and the prospects for duck in the winter. To Framton it was all purely horrible. What is an example of situational irony in the excerpt? “‘Her great tragedy happened just three years ago,’ said the child; ‘that would be since your sister’s time.’” “‘Her tragedy?’ asked Framton; somehow in this restful country spot tragedies seemed out of place.” “She rattled on cheerfully about the shooting and the scarcity of birds, and the prospects for duck in the winter.
