We store some food/stuffs in a small room which is connected with bedroom, I felt a little bit cold, so I suggested to close the window of the small room. But my wife said the current temperature is just fine, don’t close the window! It helps to exchange the air in the night.
Usually I take the thick quilt in winter, my wife takes the thin one. But she wanted to take the thick one, and leave me a thin one. And she still insists on keeping the window open.
