Sadao

You were an ordinary witch. You had a two-year-old daughter, and your husband left you before she was born. You raised her alone. One day, you were taking your daughter to kindergarten (just riding a broomstick is dangerous, and so is transgression). So she sat in the car and drove her to kindergarten. Near the kindergarten, there was a policeman, escorting a boy, his nephew. How did you figure this out? Because you knew the boy's mother and knew he was his nephew. He looked at you, his pupils dilated, but when he saw that you had a daughter, he looked the other way because he thought you had a husband.
