Wilhelm was tired, but much too excited to sleep. He lived over again in thought the last few months, and, as often happened lately, he lapsed into painful meditation on his relations to Loulou. After her departure from Hornberg she had not written to him for eight days. Then came a letter from Ostend, in which she called Wilhelm "Sie." She said she was very sorry for this, that it would be painful if she called him "Du" and he did not return it, but it would be safer not to do so, as his answer would certainly be read by her mother, and perhaps by her father also, and they would not wish them to say "Du" to each other. Already this change of tone between them cut Wilhelm to the heart, but almost more still the contents of Loulou's letter. She spoke a little of the sea, whose breakers continually sounded in her soul, and her thoughts, which accompanied them like an orchestra; she seldom mentioned the delightful time in the mountains of the Black Forest, which remembrance he carried always with him; but a great deal about the Promenade, the concerts, the Casino balls, her own charming bathing and society toilettes, and those of extravagant Parisians, who tried by incredible mixtures of colors and style to outstrip each other. She wrote particularly about her acquaintances with celebrated people, and her personal following, and for the rest she hardly missed expressing in any of her letters her regret that he was not with her, and enjoying her varied life. Often in the letter there was a flower, or a piece of wild thyme, which betrayed an undercurrent of feeling beneath the shallowness of the words, and once she sent him her photograph with the words "Loulou to her dearest Wilhelm." So he gathered from her frivolous letters much that was unspoken, and through signs and indications believed that her feeling for him was there and gained strength. His answers were short and rather compressed. The knowledge that they would be seen by her prosaic parents, and that Loulou herself would hardly trouble to read anything in the midst of her whirl of gayety, deprived him of words, stopped the flow of his feelings, and turned his expressions into mere Philistinisms. But, on the other Land, Loulou's mother was delighted to have another correspondent, and so she wrote to him often. These perfumed letters from Ostend refreshed him by the remembrance of the lovable face with the dimples, bringing back again the whole charm of the Hornberg days. At the end of September came the announcement that the Ellrichs had left Ostend, and were going to pay a visit for a fortnight to friends in England, and toward the middle of October a letter, bearing the Berlin postmark, arrived in Loulou's handwriting. It said: "DEAREST WILHEM: We came home to-day. I cannot sleep until I have written to you. Come to see me quite soon. Will you not? How glad I am! Are you glad too? A thousand greetings. LOULOU."
