When I am about to enter a main entrance, I must first ask if someone is inside. Before entering a room, I must first make myself heard, so that those inside know someone is approaching. If someone asks who I am, I must give my name. To answer ‘It is me’ or ‘Me’ is not sufficient. Before borrowing things from others, I must ask for permission. If I do not ask, it is stealing. When borrowing things from others, I will return them promptly. Later, if I have an urgent need, I will not have a problem borrowing from them again.
