The first sign that two people no longer stand to each other in the relation of mere acquaintances is generally that the tones of their voices change, while they feel a slight and unaccountable constraint when they happen to be left alone together. Two days passed after the little incident which had occurred at dinner before Clare and Johnstone were momentarily face to face out of Mrs. Bowring's sight. At first Clare had not been aware that her mother was taking pains to be always present when the young man was about, but when she noticed the fact she at once began to resent it. Such constant watchfulness was unlike her mother, un-English, and almost unnatural. When they were all seated together on the terrace, if Mrs. Bowring wished to go indoors to write a letter or to get something she invented some excuse for making her daughter go with her, and stay with her till she came out again. A French or Italian mother could not have been more particular or careful, but a French or Italian girl would have been accustomed to such treatment, and would not have seen anything unusual in it. But Mrs. Bowring had never acted in such a way before now, and it irritated the young girl extremely. She felt that she was being treated like a child, and that Johnstone must see it and think it ridiculous. At last Clare made an attempt at resistance, out of sheer contrariety. "I don't want to write letters!" she answered impatiently. "I wrote two yesterday. It is hot indoors, and I would much rather stay here!" Mrs. Bowring went as far as the parapet, and looked down at the sea for a moment. Then she came back and sat down again. "It's quite true," she said. "It is hot indoors. I don't think I shall write, after all." Brook Johnstone could not help smiling a little, though he turned away his face to hide his amusement. It was so perfectly evident that Mrs. Bowring was determined not to leave Clare alone with him that he must have been blind not to see it. Clare saw the smile, and was angry. She was nineteen years old, she had been out in the world, the terrace was a public place, Johnstone was a gentleman, and the whole thing was absurd. She took up her work and closed her lips tightly. Johnstone felt the awkwardness, rose suddenly, and said he would go for a walk. Clare raised her eyes and nodded as he lifted his hat. He was still smiling, and her resentment deepened. A moment later, mother and daughter were alone. Clare did not lay down her work, nor look up when she spoke. "Really, mother, it's too absurd!" she exclaimed, and a little colour came to her cheeks. "What is absurd, my dear?" asked Mrs. Bowring, affecting not to understand.
