What a strange, unaccountable character! — for with all these symptoms of profligacy at ten years old, she had neither a bad heart nor a bad temper; was seldom stubborn, scarcely ever quarrelsome, and very kind to the little ones, with few interruptions of tyranny; she was moreover noisy and wild, hated confinement and cleanliness, and loved nothing so well int he world as rolling down the green slope at the back of the house.
– Jane Austen, Northanger Abbey
