PART A: What is the central idea of the text?

Explanation:

Patrick treats her very brusquely telling her to sit down. After he has a second drink and refuses dinner for a second time, he tells her to “sit down…just for a minute, sit down.” This is the first direct order he has given her, a break from the placid personality she has come to expect. He then tells matter-of-factly that he is leaving her. Her actions show her changing from adoring to horrified to robotic.
