They were constantly trying best each other on any subject that happened to come up. My mother was an amature genealogist and her friend thought the whole idea was just asinine. The relationship was never quite the same after the friend told my mother she had thrown out family letters and pictures because they were just cluttering up the place. She told me she did it because she knew it would make my mother angry! These two saw each other probably 2-3 times a month for over 40 years, so nothing of this nature surprises me. Some people are just that way..they have to be on top. Mrs Lucas is now on top, as not only is her daughter getting married first, but she will inherit property Mrs L may have been coveting for years. She knows just what buttons to push with Mrs Bennet, and may have been waiting for years to have an opportunity.
