She stood still, staring at this letter, for she could scarcely countenance her own thought. She had observed often, in spite of all their caution, how friendly Aileen had been to him and he to her. He liked her; he never lost a chance to defend her. Lillian had thought of them at times as being curiously suited to each other temperamentally. He liked young people. But, of course, he was married, and Aileen was infinitely beneath him socially, and he had two children and herself. And his social and financial position was so fixed and stable that he did not dare trifle with it. Still she paused; for forty years and two children, and some slight wrinkles, and the suspicion that we may be no longer loved as we once were, is apt to make any woman pause, even in the face of the most significant financial position. Where would she go if she left him? What would people think? What about the children? Could she prove this liaison? Could she entrap him in a compromising situation? Did she want to? She saw now that she did not love him as some women love their husbands. She was not wild about him. In a way she had been taking him for granted all these years, had thought that he loved her enough not to be unfaithful to her; at least fancied that he was so engrossed with the more serious things of life that no petty liaison such as this letter indicated would trouble him or interrupt his great career. Apparently this was not true. What should she do? What say? How act? Her none too brilliant mind was not of much service in this crisis. She did not know very well how either to plan or to fight. The conventional mind is at best a petty piece of machinery. It is oyster-like in its functioning, or, perhaps better, clam-like. It has its little siphon of thought-processes forced up or down into the mighty ocean of fact and circumstance; but it uses so little, pumps so faintly, that the immediate contiguity of the vast mass is not disturbed. Nothing of the subtlety of life is perceived. No least inkling of its storms or terrors is ever discovered except through accident. When some crude, suggestive fact, such as this letter proved to be, suddenly manifests itself in the placid flow of events, there is great agony or disturbance and clogging of the so-called normal processes. The siphon does not work right. It sucks in fear and distress. There is great grinding of maladjusted parts—not unlike sand in a machine—and life, as is so often the case, ceases or goes lamely ever after.
