Five years ago, I negotiated the monthly parking fee down from 1,200 yuan to just 320 yuan for 83 households in my residential community. Whenever someone changed their license plate or got stuck outside the parking barrier in the middle of the night, they would call me. In return for managing the parking lot, I was given a rent-free parking space. But Luo Man, a new neighbor who had only moved in three months earlier, accused me of taking advantage of free parking for five years and demanded that I pay back 72,000 yuan. She claimed she could negotiate an even lower monthly fee of 280 yuan. Seventy-nine households signed the agreement, and I signed over my responsibilities. It wasn't until the following day, when the parking barrier stubbornly refused to open, that the neighbors finally remembered to ask: Now that Xu Zheng has stepped down, does the 320-yuan agreement still stand?
