'A man has kept his 14-year-old daughter Linda locked up in his house for her entire life; he is the only person with whom she has interacted, and he has deliberately communicated with her in 'mixed-up English', using words in opposite contexts (e.g. interchanging the words 'yes' and 'no') to demonstrate a point about the way a person learns to speak. A young plumber visits and is horrified, and the father gives him permission to attempt to explain the experiment to Linda, convinced that she will not be able to comprehend what he is telling her; he tries several times, and as the story progresses she shows signs of beginning to understand what her father has done.

'At the climax of the story, the house burns down with Linda's father trapped inside. When the fireman asks Linda if anyone is inside the house, she tells him 'no'; but, her meaning is left ambiguous.' (https://en.wikipedia.org/wiki/Quirky_Tails)
