Had Beef with My Technology Teacher.

So… I got a zero for an assignment for forgetting my headphones. Silly right? The next day, I asked her for an extra assignment to fix up my grade. She angrily stated that she won’t. She threatened me with a detention. Me confused, walks out of her classroom. The next day, I asked her again… (She had a better mood) But this time… She ANGRILY jumped from her chair and started staring at me dead in the eyes for 5 seconds. That felt like an hour tbh. Then, she yelled at me for absolutely no reason, and threatened me with a visit to the principal’s office and a detention. I walked out of her room, angry. And yes, this all happened today and yesterday.

Who was right here, and what did I do wrong?
