Answer:
The author has a good reason to be biased
Step-by-step explanation:
"Someone’s feelings, opinions, and beliefs about a subject represent that person’s bias. Bias shapes people’s perceptions, or views, of events. Because of bias, people are more likely to tell only one side of a story—the side that reflects their own particular point of view. When people record their private thoughts, they often write with plenty of bias about a subject. After all, many people who keep diaries never intend to share their writings with others, so why should they present any view other than their own?"
