Marie is a student who usually does well in school, but does not always obey the rules at home. One day, her mother asked her to come home early from playing to watch her younger sister, but Marie forgot and went swimming with her friends instead. When she returned home, she discovered her sister had fallen and was crying. Marie realized that if she had obeyed her mother, she could have prevented her sister from getting hurt. She apologized to her mother for disobeying, and promised to follow rules better in the future.
