She'd randomly check bags and desks during tests "to maintain academic integrity." But everyone knew she just loved catching kids with phones.
She'd been a security consultant before teaching and bragged about it constantly. Last semester, she caught seventeen students and displayed their phones in a locked cabinet like trophies.
My mom was in the hospital with complications from surgery. What started as routine gallbladder removal had turned into a nightmare when they discovered an underlying condition. The doctors said they might need to reach me during school hours if anything changed.
I explained this to Mrs. Brennan before class, showing her the hospital paperwork.
"Rules are rules," she said without looking up. "Your mother's condition doesn't change school policy."
I couldn't believe it. My dad wrote a note requesting an exception, but she refused. The principal was out for two weeks, and the vice principal always backed teachers' decisions.
That night, my mom's condition worsened. The doctors found internal bleeding they couldn't explain. I sat by her bed until 3 AM, watching nurses rush in and out.
"Go to school tomorrow," Mom whispered. "I'll be fine."
She wasn't fine. And I couldn't risk missing an emergency call.
That's when I remembered Mrs. Brennan's obsession with her classroom calculator collection. She had dozens displayed on shelves – everything from basic models to fancy graphing calculators.
I went to RadioShack and bought an old-school calculator with big buttons and a solar panel.
At home, I carefully opened it, removed the circuitry, and fitted my phone inside. I worked through the night, using my dad's precision tools. I even made sure the solar panel still lit up by wiring it to a tiny LED.
The next morning, my cousin who worked at the hospital texted me: "Your mom's being prepped for another procedure. Doctors concerned."
I nearly threw up from anxiety.
Walking into chemistry, I noticed Mrs. Brennan eyeing everyone suspiciously. She'd installed a signal detector in the classroom that supposedly blinked when it detected phone transmissions.
I'd thought of that too. Inside my calculator, I'd wrapped my phone in aluminum foil - a makeshift Faraday cage that would block signals until I needed them.
Twenty minutes into class, Mrs. Brennan announced a surprise desk check. When she reached Kevin next to me, she confiscated his TI-84 because "it looked suspicious."
She stopped at my desk, rifling through my backpack and pencil case.
"What's this?" she asked, picking up my calculator.
"It's my calculator," I said innocently. "For the stoichiometry problems."
She pressed a few buttons, watching numbers appear on the tiny display sticker I'd created. The phone inside remained silent thanks to vibrate mode.
"Carry on," she said, looking disappointed as she moved to the next student.
Ten minutes later, my "calculator" vibrated. The hospital. My mom needed emergency surgery.
I raised my hand. "Mrs. Brennan, may I use the restroom?"
In the hallway, I called back immediately. After talking to the doctor, I returned to class in tears.
Mrs. Brennan pulled me aside. "What's wrong?"
"My mom," I choked out. "Emergency surgery. I need to go."
"How did you find out?" she demanded suspiciously.
I held up my "calculator" and slid the case open, revealing my phone.
Her face turned three different shades of red. "You deliberately violated school policy!"
The entire class watched as I stood up straight. "My mother might be dying. Write me up if you want, but I'm leaving."
The next day, Mrs. Brennan's zero-tolerance policy was officially amended to include medical exemptions.
