You had been ten minutes late to class, you hadn't thought it a big deal but it earned you a week's worth of detention with Professor Snape.

Unfortunately for you and your sleep schedule, he chose the time for your detentions to be set at ten at night. Usually, you'd be in bed at that time, or up to something with your friends.

As of now, you were waiting outside of his office door, with he seemed to be taking his time to answer but that also gave you time to look around the potions classroom.
