The reading question mentioned that Cockroach's mother likes to eat fish heads, but I'm not sure if she really likes to eat fish heads. In novels, the actions and motives of the characters are often complex and diverse, and cannot be simply attributed to a single reason. Perhaps Cockroach's mother's love for fish heads was just a facade. She might have other motives and personality traits. For example, she might be a conservative mother who was not willing to accept new things and changes. Even if she liked fish heads, it might be because it was her traditional hobby and not the real reason. Or maybe Cockroach's mother was a person who liked to eat fish heads. This was her personal preference and habit. In novels, the likes and actions of the characters are often related to their personalities and backgrounds, so this behavior may also be a kind of character setting and plot arrangement. In short, it was uncertain whether Cockroach's mother really liked to eat fish heads. It depended on the plot and character settings of the novel.
