After my maternal aunt's family moved into our home, they became picky about food and drinks, recklessly left the air conditioning running, and monopolized the computer. My cousin, Liu Hao, secretly took our tea and perfume, pretended to be the homeowner while going on a blind date, and even introduced my mother as a housekeeper. My newlywed wife, Xia Qing, calmly set a trap, exposing their lies in front of everyone with social media screenshots, payment records, and the property deed, forcing them to pay compensation. When my aunt demanded 30,000 yuan as a so-called moving-out fee, she was promptly put in her place. My mother finally woke up and started keeping track of every expense, while my father let go of his unreasonable obsession with saving face. Together, our family of four drove out our greedy relatives and established new house rules: kindness should be reserved for those who know how to be grateful.
