Answer: The word "rivets" can suggest a sense of permanence and fixation. It is often associated with the act of fastening or securing something tightly. If the speaker's memories have now changed, the word "rivets" may indicate that these memories were once firmly fixed or deeply embedded in the speaker's mind but have now become altered or loosened.
Explanation:
For example, if the speaker initially held strong and unwavering memories of a particular event or person, the word "rivets" could suggest that these memories were once tightly bound and unchanging. However, if the speaker's memories have now changed, it could imply that the once firm grip of these memories has weakened, allowing for new perspectives, understandings, or interpretations to emerge.
