“The Dursleys had everything they wanted but they also had a secret, and their greatest fear was that somebody would discover it. They didn’t think they could bear it if anyone found out about the Potters. Mrs. Potter was Mrs Dursley’s sister, but they hadn’t met for several years; in fact, Mrs Dursley pretended she didn’t have a sister, because her sister and her good-for-nothing husband were as unDursleysish as it was possible to be.”
