Madam, Something Hasn't Been Right Lately

On an ordinary day, I found that my wife looked at me a little strangely. When I think about women, my mood is always uncertain, so I can just buy her favorite roast chicken and go back to comfort her. A week passed. The food was still being cooked and the clothes were being washed, but the house was so quiet that the only sound was my own voice. She took the tea that was handed to me, but never looked at me again. A month passed. This morning I opened the door - a piece of paper was placed on the table. It's over, madam... She's not going to leave me, is she?
