Papa Jiao was quick to act. Since he had already decided to ask Wei Ling to look after the children, he called him straight after lunch. Those were non-working hours, a good time to look for people.
Because of Zheng Tan, Papa Jiao would stop and chat with Wei Ling when they ran into each other. Their topic of conversation revolved mostly around Zheng Tan, but seemed to have contained other stuff as well. Zheng Tan did not know for sure, but they might have talked about where Wei Ling was going to work in the future.
Wei Ling had replaced his PHS with a cellphone, which meant that Zheng Tan didn’t have to listen to him swear anymore.
Wei Ling agreed immediately to come take care of the children in the evening. He was busy during daytime but had nothing to do at night anyway.
