She had wondered at times just how important the sex relation was in her attachment to Frank. It was of major importance, of that she was sure, but was it the key? If they drifted apart physically, would the other aspects of the relationship vanish? She thought not, but she certainly would not have been willing to put it to the test. Frank Corson was through looking out the window now and he began pacing nervously. "Sure--so it's fine to be a doctor. It's the sure-fire answer for later in life. But what about now? What about this crawling up the ladder inch by inch?" He turned on her defiantly. "Living on your money!" "You aren't!" "All right. Maybe not technically." He looked around the room resentfully. "Using your apartment for--" "Frank! When I have guests, do they hesitate because my apartment is nicer than--?" She knew she'd hurt him even before his head came around and his eyes narrowed. "So that's what it really is to you!" She'd said the wrong thing, but even as she sprang up from the bed she felt that it made no difference because he would have found something else. "I didn't mean it that way. You know I didn't." She ran to him and laid her hands on his chest; his eyes traveled down her naked body and his mind struggled. His expression said it was a little unfair of her to come so close and stand that way, nude and beautiful and eager, in front of him, especially when he had a point to make. "I'm a pauper trying to keep up with the rich." She knew how to break his mood now. She smiled and pressed against him lightly and said, "Uh-huh, but what a pauper. And darling, money wouldn't change that part of it a bit." He drew her to him violently. The impact of their bodies hurt her ribs but she gloried in the pain. She let her knees weaken and sank to the thickly carpeted floor, bringing him down with her. She knew Frank's outburst was over--at least for that day. Later, on the bed, he opened his eyes sleepily. "What time is it?" "A little after ten." "That gives us almost two more hours." He looked out over the East River. "It's beautiful." "_Isn't_ it?" "If I went right into research--took a job somewhere--I could afford to give this to you." She thought of saying, _But, darling, I've got it already_, and decided a change of subject would be more judicious and said, "You _were_ kidding last night, weren't you?" "Kidding?" "About the man with two hearts." Frank grinned a little sheepishly. He was extremely handsome and totally unconscious of it, and when he grinned that way it made him look like a little boy caught stealing jam, and Rhoda always wanted to hug him. But she forebore as he said, "It does seem a little silly, doesn't it?" "You'd know more about that than I do. Is it silly?" "Let's say the chances of such a thing happening are rather remote." "You only used your stethoscope last night?" "That was all. I went by what I heard." "What will you do now? X-ray?"
