Final answer:
The sentence that shows Janine and Jamie respect each other's privacy is not given, but examples of respectful silence, courtesy, and non-intrusion in the excerpts reflect how privacy is respected in relationships.
Step-by-step explanation:
The sentence that best shows that Janine and Jamie respect each other's privacy is not explicitly provided in the excerpts. However, to infer their respect for privacy, one could look at the actions and reactions of characters in similar situations from the excerpts.
For instance, the respectful silence between characters, the courtesy of thank you notes, and intentional avoidance of intrusion into one another's personal matters are all indicative of respect for privacy in relationships. Although none of these examples are directly about Janine and Jamie, they reflect the subtlety with which respect for privacy can manifest in a narrative context.
