After Fang left, Zheng Tan stayed on the balcony. He took a look whenever a car entered the quarters.
Papa Jiao's car still hadn't arrived when he had to leave to pick up Youzi.
Papa Jiao called during lunch to say he wouldn't be coming to lunch today, so Zheng Tan guessed he was still at the car dealers. He had to deal with this during work hours and probably left all his work to Yi Xin and Su Qu.
He stayed inside the quarters that afternoon to wait for the car. He wandered around a bit, then picked a tree and took a nap.
It was five in the afternoon when Papa Jiao finally came home. However, he came home on foot. Zheng Tan looked at him. There was no car.
Where was the car?
Papa Jiao gave no explanation, so Zheng Tan planned to eavesdrop that night. Papa and Mama Jiao would sometimes discuss matters after the kids went to bed.
After dinner, he watched television with the kids until 9. He waited until they were in bed before acting on his plan.
