Answer:
One example of Nadia realizing that her actions can affect how other people feel and behave is when she learns that her friendship with Addie is causing friction between Addie and her other friend group. Nadia realizes that her presence is making Addie feel torn and left out, and she decides to step back and give Addie space to work on repairing her relationships with her other friends. This shows that Nadia has become more aware of how her actions can impact others and is willing to take responsibility for her role in the situation.
