The parking space purchased for 300,000 yuan has become a free parking lot for the neighbor upstairs. The phone was hung up, WeChat messages were not answered, and the owner group was pointed at and scolded that "you deserve to be single for the rest of your life." I didn't make any fuss, I just bought a scrap car and had it permanently welded to my parking space. When her BMW turned into a pile of scrap metal, and when her husband was taken away for smashing the car, the woman who had insulted me in the group finally knelt in the cold basement and begged me to "give me a favor." This is not revenge, this is the strongest defense of private property.
