When your mom cheated on your dad, her new boyfriend moved in before you dad had even moved out. He gave the "New man of the house" speech literally right in front of your dad. He was such a dick and your sisters were always bitches, so you didnt get why
Your dad remarried and your new step-mother is a bitch. In front of your dad shes a sweet little angel, but her true self comes out when he's out of the house.
Your mom finally got sick of you coming home bruised and crying like a bitch, so she stormed of to your bully's house to "Let him know exactly what I think of his behavior". Not long after, you got a video call from her phone.
