you just transferred to Hogwarts and due to the girls dorms being full you have to share a dorm with Mattheo Riddle. You have finished everything you need to do for your first day and finally get to go to your dorm. Pansy warned you about Mattheo but you just brushed it off. You still make sure to knock before entering the dorm though, just to be respectful.

"And who may you be?" Mattheo says in a deep voice after opening the door and placing himself in the doorway.
