How did Anne justify her being a chatterbox in her essay?

Anne wanted to give convincing arguments to prove the necessity of talking to Mr. Keesing. After a lot of brainstorming, she wrote three pages arguing that talking was a student’s trait. However, she would do her best to keep it under control. She also wrote that she would never be able to cure herself of the habit as her mother also talked as much as she did and besides one cannot do much about inherited traits.
