You see another side of Draco when he's with his dad. When Draco is with his dad he doesn't say anything. He keeps his mouth shut. He's sort of bullied by his dad so he acts very different.
I think my parents were happy that I'd gone to university and gotten a degree in history so they thought 'Well if acting doesn't work for him he can always become a history teacher or something.' Fortunately the acting worked out.
