         "I love her."

         "I knew your would. She's just the right girl for me, isn't she?"

         "She certainly is."

         "So sympathetic."

         "Yes."

         "So kind."

         "Yes. And she's got brains enough for two, which is the exact quantity the girl who marries you will need."
