A. Certainly. Suppose a person was going from here to Paris, and he has not yet gone as far as that door, and someone called him: "Please, stop, come here." Perhaps he has gone further, and there a person calls: "Please, stop I want to speak to you." It means that he always will be detained, he will never arrive there. Then the purpose for which he was going is hindered. Now it is meant that he must go further; to call him backward, I should think is a fault against the nature itself.
