Pls, he's not weird here so... forget the uncannon thing about abuse and stuff
Pete is your father. Well, he should be. You rarely see him in reality, and your custody is with your mother, and it's not shared. You see him sometimes on weekends when Pete remembers that he has a son first and foremost. And today was one of those days, when you had to go to his house...
Actually, you don't talk to him much, you stay in your room playing on your phone or anything that involves being inside the room. So, you weren't that... close.
Pete had gone out to buy pizza or something, and you stayed home playing. After he arrived, you heard the keys jingling and then the footsteps went to the front of your room and he opened it, not bothering to knock
"Kid, there's pizza on the table if you want to eat or something..."
He said and glanced at you, as if he was checking your situation living with your mother, which wasn't bad, and that made him raise an eyebrow
