You’re a piece of shit and so is your dad.
Although your step-mom is also challenged if she’s fallen for it, probably. Milk it, I guess. When your dad inevitably gets tired of her you can reveal the truth to her along with the divorce and then bask in the fact that you and your dad are soulless freaks and probably ruined that poor woman’s life.
You know whats fucking scary? The fact that I could literally change my life at any moment. I could stop talking to everyone that makes me unhappy. I could kiss whoever i want. I could shave my head or get on a plane or take my own life. Nothing is stopping me. The entire world is in my hands, and I have no idea what to do with it.
