For the next half hour, the compromise held. I opened my book and tried to lose myself in the story, even dozed a little. Then, with no warning—bam!—the seat slammed backward again, pinning me as tightly as before.

I let out a low groan. She didn’t move. Clearly, courtesy had failed.

I sat still for a moment, breathing evenly, then glanced at the tray table in front of me. The flight attendants had just come by with drinks, and a small plastic cup of tomato juice rested on my tray. The idea arrived fully formed, and I couldn’t resist.

Carefully, deliberately, I slid the cup to the very edge of the table, just beneath the back of her seat. I sat back, hands folded, eyes innocent.

Minutes ticked by. The hum of the engine was steady, passengers murmured, and the cup of juice waited like a silent trap. Then—movement. She shifted, pushing her seat back further, and with a quick wobble, the cup tipped.

The red liquid splashed across her pale handbag and dotted the hem of her cardigan.

She bolted upright with a shriek.
“What is this?!” She twisted around, glaring at me.

I widened my eyes. “Oh no! I’m so sorry. You leaned back so suddenly, and the tray is tiny—I couldn’t stop it.”

Her face reddened, mouth opening and closing. “Flight attendant!” she barked, waving her arms.

Marta returned promptly. “What happened here?”

The woman gestured wildly. “He spilled juice all over me!”

I held up my empty hands. “I was just sitting, drinking quietly. The seat moved back, and well, the cup tipped. Physics, I suppose.”

For a split second, Marta’s lips twitched, as though she was suppressing a smile. Then she nodded briskly.
“I see. Here are some napkins, madam. And perhaps it’s best if you keep your seat upright for the remainder of the flight, to avoid further accidents.”

The woman sputtered but accepted the stack of tissues. She dabbed at her bag in silence, muttering under her breath.

From that moment until we landed, her seat remained perfectly vertical.

I leaned back as much as I could in my narrow space, opened my book again, and let the minutes drift past. Outside, the clouds slid beneath us, soft and harmless, while inside the cabin, justice had been quietly, if messily, served.
