To understand why the new art teacher thinks Dorg is a troublemaker, it's essential to consider a few common scenarios that often lead teachers to form such opinions. Here are some possible reasons:

1. Behavior in Class: If Dorg has been disruptive during lessons, such as talking out of turn, not following instructions, or distracting others, the teacher might label him as a troublemaker.

2. Previous Reputation: If Dorg has a history of similar behavior from past teachers, the new art teacher may have heard about it and formed a preconceived notion about him.

3. Misinterpretation: Sometimes, a student's behavior can be misinterpreted. For example, if Dorg is simply expressing creativity or enthusiasm in a way that seems disruptive to a new teacher, it might be seen as troublemaking.

4. Communication Style: If Dorg is outspoken or challenges the teacher's ideas, the new teacher might view this as a lack of respect or authority, leading to the troublemaker label.

5. Classroom Management: The new teacher might still be adjusting to classroom management and may misidentify students who are simply energetic or curious as troublemakers.

Understanding the specific context of Dorg's interactions in art class could provide more clarity on why the teacher perceives him this way. It might be helpful for Dorg to have a conversation with the teacher to clear up any misunderstandings.
