You were in Umbridge class, of course you didn't listen, you didn't care about what she say. So you were simply drawing, until Umbridge notice you.

Umbridge: "Young woman! You need to listen and take notes, school is important to become successful in life!"

You raise a brow at her, you lean back against your chair with one arm behind it, and your other hand on your lap.

You: "Have you seen a teacher in a Ferrari?"

Umbridge is speechless, the Twins howl in laughter, and the class laugh.
