story = "Mr. and Mrs. Dursley, of number four, Privet Drive, were \
        proud to say that they were perfectly normal, thank \
        you very much. They were the last people you’d expect to be involved in anything strange or mysterious, because they just didn’t \
        hold with such nonsense. \
        Mr. Dursley was the director of a fi rm called Grunnings, which \
        made drills. He was a big, beefy man with hardly any neck, although he did have a very large mustache. Mrs. Dursley was thin \
        and blonde and had nearly twice the usual amount of neck, which \
        came in very useful as she spent so much of her time craning over \
        garden fences, spying on the neighbors. The Dursleys had a small \
        son called Dudley and in their opinion there was no fi ner boy \
        anywhere."
