" I was such a foolish girl - girls are foolish, Mr. Satterthwaite. They are so sure of themselves, so convinced they know best. People write and talk a lot of a ‘woman’s instinct.’ I don’t believe, Mr.Satterthwaite, that there is any such thing. There doesn’t seem to be anything that warns girls against a certain type of man. Nothing in themselves, I mean. Their parents warn them, but that’s no good - one doesn’t believe. It seems dreadful to say so, but there is something attractive to a girl in being told anyone is a bad man. She thinks at once that her love will reform him. "
