Sarah is shopping with her grandmother in a city mall. As they are walking down the hallway, they pass by a group of boys who are making noise and being disruptive. Sarah's grandmother, who is elderly and frail, is startled by the noise and stops to catch her breath. Mark, Sarah's boyfriend, who is walking behind them, bumps into Sarah's grandmother and they both stagger to the ground.
Sarah is shocked and horrified by Mark's behavior. She helps her grandmother up and apologizes to her for Mark's actions. Mark, however, does not apologize. He simply shrugs his shoulders and says, "It was an accident." Sarah is furious with Mark's lack of respect for her grandmother. She tells him that he needs to apologize, but he refuses.
Sarah is so upset by Mark's behavior that she decides to write him a letter. In the letter, she expresses her feelings of hurt and betrayal. She also tells him that she is disappointed in him for not showing respect for her grandmother. She ends the letter by saying that she needs some time to think about their relationship.
The letter is a heartfelt expression of Sarah's love and belief in Mark's potential to be a better person. She tells him that she still loves him, but that she cannot be with him if he does not change his ways. She encourages him to introspect and consider his actions, while expressing her unwavering support and belief in him.
