The School’s “Problem” Student

Everyone knew me as the problem. The kid who always ended up in the principal’s office. Mrs. Martinez already had my file ready, and teachers sighed the moment my name appeared on the list.

You again, Mateo,” Mr. Ruiz said one Tuesday, spotting me in the bathroom with my face bruised from another altercation. “What happened this time? Another fight without reason?”

I nodded silently, wiping my face. I never explained.

“I don’t get it,” he continued, disappointment heavy in his eyes. “You have good grades when you try. You could be a great student. Why choose this path, Mateo?”

Because I have no choice, I thought. I just murmured:

“I don’t know.”

Three days of suspension. Again.

What no one knew was that every fight, every punishment I silently accepted, was for her. For Luna.

My sister was twelve, two years younger than me, and had cerebral palsy. She used a wheelchair, sometimes struggled to speak when nervous. The sweetest girl you could imagine, with a smile that could light a room. For me, she was perfect. But at school, some saw her as an easy target.

The first time I heard Diego and his friends mocking her in the yard, something inside me snapped.

“Look at the dummy,” Diego sneered, mimicking her movements. “She can’t even speak properly.”

Luna’s head hung low, eyes full of tears. She tried to answer, but the words wouldn’t come — which made them laugh even harder.

I don’t remember how I reached them. I just know I stepped in.

Stop!” Luna cried through her sobs. “Mateo, no!”

But I didn’t stop until the teachers intervened.

In the principal’s office, Luna was there, in her chair, with Mom at her side. Her eyes were tired from long days of work.

“Mateo got in trouble for no reason,” Principal Martinez said. “We cannot allow this behavior.”

“I… I started it,” Luna said suddenly, trembling. “It was my fault.”

I froze. My sweet little sister, trying to protect me.

“No, Luna—” I started.

“It’s true,” she insisted. “I… said something wrong and—”

“Enough,” I interrupted, glaring at the principal. “It was my fault. Mine alone.”

Mom looked at me with those eyes that always saw more than I wanted, but said nothing.

A week of suspension followed.

That night, Luna rolled into my room.

“Why do you do it?” she asked softly. “I know… you’re protecting me. But they punish you for me.”

I sat beside her chair, taking her hand.

“Because you’re my sister. No one has the right to hurt you.”

“But… you’re hurting yourself,” her eyes glistened. “Everyone thinks you’re bad. But you’re not.”

“I don’t care what they think,” I said, squeezing her hand. “I care about you.”

“What if I tell? If I say the truth?”

“No,” I said firmly. “Then they’d go after you harder. At least this way, they respect you when I’m around.”

It was true. Once I started defending her, no one dared touch Luna. My reputation, bad as it was, became her shield.

Months passed. Every insult at Luna ended with me in the principal’s office. My record grew. The universities I dreamed of seemed farther away.

But Luna came home smiling. Making friends. Participating in class without fear.

And it was worth it.

One day, Mr. Ruiz stopped me after class.

“Mateo, be honest with me. I won’t report this, I promise. I just want to understand. Why do you keep getting in trouble?”

I looked at him. Something in his eyes was genuine.

“For someone who can’t defend themselves,” I said.

He frowned, confused. Then recognition softened his face.

“Your sister… Luna.”

I didn’t need to say more.

“Mateo… there are other ways to protect her. Ways that won’t close doors for you.”

“Maybe,” I said. “But none work as fast. None keep her safe right now.”

He sighed.

“Let me help.”

I didn’t understand at first. Then the school launched an anti-bullying program — teachers watched more closely, consequences were real. Mr. Ruiz never reported me, but he found a way to help.

Things slowly improved. But my reputation remained.

Now, as I sit in the principal’s office again after defending Luna from someone who didn’t understand her, I know what’s coming: more punishment. More calls home. More doors closing.

But when I leave, I’ll walk past Luna’s classroom. She’ll be laughing with her friends, a twelve-year-old girl with no fear.

And I’ll know it was worth it.

Because I’m the school’s “problem” student.

And the best brother I can be.

Those two things? In the end, they’re one and the same.
