Just a reminder. Trying to remind men to close the door. You can say please close the door or close it directly to remind men to pay attention to privacy and etiquette. Stay calm and avoid overreaction. Don't attack or criticize men, keep calm, so as not to cause unnecessary contradictions and disputes. Try to avoid meeting men in men's and women's bathrooms.
