While Von Gleichen, the Danish envoy, was negotiating with Choiseul as to the manner in which Christian was to be received, he was urged to obtain leave that the two monarchs should meet alone on the first interview, that when the doors were shut the King of France should give the title of Majesty to him of Denmark, and that afterwards the latter should remain in the strictest incognito. M. de Choiseul answered Gleichen that, "though he had his Majesty's commands to assent to everything requested in the matter of etiquette, he ought to be aware that his demand was impossible, as the King of France had never remained alone for a single moment in his life, not even in his garderobe, and that he had no power to expel from his chamber persons who by right of office had a claim to remain in it." The first interview, therefore, took place in the presence of all the chief personages, but when, on the next day, Louis XV. returned Christian's visit, accompanied by a few princes of the blood and his whole court, the youthful monarch ran to meet the King of France, took his hand, and, walking very quickly, drew him into his cabinet, the door of which he locked. All this was done so promptly, that the Duc d'Orléans, pushed by the crowd who were eager to follow, ran against the door, and thus Louis XV. remained alone with a stranger for the first time in his life. The two monarchs conversed together for some time, and were mutually charmed; but afterwards Christian said to Gleichen, "Do you remember what you wrote us about the impossibility of a King of France remaining alone? I succeeded better than you, for I took a pleasure in it."[82] During this interview the King of France expressed his regret that the deep mourning for his consort, Maria Leczinska, prevented him from celebrating the visit of his brother, at which he was greatly pleased, by court festivities, but he had taken care that his Danish Majesty's stay in Paris should be rendered as pleasant as possible. As he was aware that his beloved guest was fond of theatres, he had sent his commands both to the Comédie Française and the Opéra, that during the Danish king's presence only such pieces should be performed as his exalted guest wished to see. Louis XV. conversed with the perfect courtesy of a French courtier. "In the year 1717," he said, "my predecessor on the throne of France had the felicity of seeing Peter the Great here, and I have great pleasure in being able to embrace Christian the amiable. How young you are! I could be your grandfather." "I should esteem myself most fortunate if I were your grandson," Christian replied. When the French king introduced his guest to the ladies of the court, he noticed that Christian paid special attention to Madame de Flavecourt. Hence he drew him on one side, and asked him, "How old do you take that lady to be?" "Thirty, at the most," Christian remarked. "She is above forty," said Louis.
