Coincidentally, this policeman was the one who took me to the Child Protective Service before.
My dad also complained, "Sir, it's not against the law for me to cheat on my wife. You have no right to detain me, right?"
"Yet, fighting in public will endanger public security."
My mother was smarter than my father. She immediately brought both of us to her and pinched our arms hard. Hence, my brother and I screamed in pain.
She said, "Sir, my children are crying so hard. They can't leave me. Please be lenient, and don't detain me."
I ripped open my sleeves, revealing the obvious wounds on my body. It caught my mother off guard.
"Sir, please take my mother away. She beats me whenever she's home."
My mother was stunned and quickly explained, "Sir, I really didn't hit her. I haven't hit her since you warned me last time."
Indeed, she didn't hit me, but I could pinch myself. I did it secretly just now.
I stared at the policeman timidly, then looked at my mother fearfully, and retracted my hand in fear. It looked very natural.
