For the rest of the week Dudley didn't see his cousin at all, his mother was cooking dinner which meant Harry must have been locked in his room because those were the only times his mother did any house work. Dudley didn't have to do any of the chores obviously but it was still annoying that his mother did because that meant her focus wasn't on him. His father was on edge all week as well, any noise that came from the cupboard caused his dad to freak out and stomp towards the door ranting about how clearly the freak hadn't learnt the lesson. Honestly in Dudleys opinion they should just let the freak out and everything could go back to normal because Dudley missed being the centre of attention, it just wasn't fair.
