What did the narrator wish to do her daddy, according to the opening line of the novel Ellen Foster? How did she propose to do this?

In the opening line of the novel Ellen Foster, written by Kaye Gibbons, Ellen reflects that when she was younger, she wished to kill her father. This is due to the fact that her father was an alcoholic and abused her mother and Ellen to the point where her mother committed suicide and Ellen ran away. She also states that her favorite way that she had thought of to kill him was by engineering a bite by a poisonous spider. She had even thought about the reaction she should have when she called for help and when they told her that he had indeed died from the bite. While ultimately she was not responsible in anyway for his death (he drank himself to death), she readily states that she is better off with him dead as it allowed her to have a better, healthier home.
