Identify who says the following quote in the play: "For me you have always had an irresistible fascination. Even before I met you I was far from indifferent to you. We live, as I hope you know, Mr. Worthing, in an age of ideals. The fact is constantly mentioned in the more expensive monthly magazines, and has reached the provincial pulpits, I am told; and my ideal has always been to love some one of the name of Ernest. There is something in that name that inspires absolute confidence. The moment Algernon first mentioned to me that he had a friend called Ernest, I knew I was destined to love you."
