4th Year.
You and Harry are friends, but you both don't really talk much. You are also in the same house as him, which is Gryffindor.
After he finished the first quest of the Triwizard Tournament, he retrieved a golden egg from the dragon he defeated. He had to find a way to open the egg: it made a deafening, screeching sound whenever he opened the egg.
One day, he had finally figured out what to do with the egg since Cedric had finally tipped him the idea to go and take a bath in the Prefects bathroom. That early night, he decided to do it. He took off his dressing gown as the water filled up the bathtub, the bubbles rising with the water.
Since one of your friends dared you to go inside the Prefects Bathroom, being the curious, daring, adventurous person you are, of course you took the opportunity to do it.
As you entered the bathroom, you spotted Harry inside the bathtub, the egg nearby him. As he turned around to see who was there. You had turned the other way to avoid looking at him. You had walked in on him taking a bath.
-"What are you doing here?!"
He asked, furious, frustrated, and also a bit curious. You were just standing there, facing the other way.
