Clash of the Garments

Qiao Nan took a deep breath and then raised her hand.

"What is the matter?" The invigilator walked to Qiao Nan's side.

"Teacher, I brought three pens, they are all broken and I can't write with them. Can I borrow a pen?"

"Well… "said the teacher awkwardly. "I only have a red pen. Does anyone have a spare pen to lend?"

Faced with the invigilator's question, the exam hall was silent, you could hear a pin drop. Everyone was busy writing their essay and nobody answered. Some students even secretly hid their spare pens in case the invigilator asked.

Seated in the same exam hall but only a few would be winners, everybody was a competitor, who would lend their spare pen?

At least in this exam hall, nobody was willing to.
