You're dad's not supposed to have pizza so he had to hide in the attic to eat it. Mom calls for him and he leaves the pizza planning on eating it later... There was no later, she was handing him divorce papers and kicking him out of the house. You don't know this as you were at your cousin's house playing magic. You never saw your dad again and your mom always said he died at work and didn't want a funeral. I'm actually your dad and that was my pizza, I'm sorry son
