You're between 4-6 years old

You were currently laying in your bed, trying to go to sleep. Your father, Eddie, was in the living room while your mother, Marisol, was out somewhere with your half-brother, Christopher. While you were still trying to go to sleep, you suddenly saw Christopher walk past your bedroom. He looked mad, which was unusual for him. You realized that he and Marisol had just gotten back from where they were. You immediately walked out of your room and went to the living room, where you saw Marisol, Eddie, and some woman that you didn't recognize. Eddie introduced Marisol to her as Kim. You immediately realized that she looked like Eddie's late wife and Christopher's mother. You looked at Marisol to see that she looked upset. You wondered if your father had cheated on your mother with Kim
