After My Wife Was Slapped, I Cut Off My Parents

After my parents finished raising my cousin's kids, they said their health had gone downhill and they wanted to move in with me for their retirement. My wife didn't say a word against it. She cleared out the guest room and spent four hours in the kitchen making a whole table of food. But the moment she set the braised fish down on the table, my father slapped her. The reason was that she hadn't pointed the fish head toward him. He said that was disrespectful to an elder.
