Qiao An walked out of the manager's office easily and saw Wei Ning sitting at the top of the stairs. She walked to Wei Ning and sat down. She took out the crumpled chewing gum, peeled off the tinfoil, divided it into two halves, and spread it in the palm of her hand. Wei Ning understood, pinched half and put it in his mouth. Looking at Qiao An's silly smile, Qiao An also put the remaining half into his mouth. Her smile was much restrained. She raised her index finger to her mouth to make a silent gesture, and then pointed downstairs, not wanting them to hear. They both covered their mouths and laughed. They noticed that their colleagues downstairs had returned to normal. They were disappointed by the manager's punishment, but they soon lost control of themselves and started laughing wildly.
From then on, Qiao An and Wei Ning became their only friends.
