He kissed her cheek softly. "I love you, too."
She cocked her head, a slight frown on her face. "Do I worry you?"
"Not at all," he answered, shaking his head slightly. "Not in the slightest, but I'm glad we are."
She grinned, leaning over him again. "Now you have to try to relax."
He cocked his head. "That's true. Not a lot of time either."
She laughed, pulling away to stretch her arms. "If I'm a genius and I think you're a genius, then it must be so."

She shook her head. "Not hardly. I know you are!"
He nodded and gave her one last kiss. "Yeah. Let's."
She kissed his cheek. "I think you're the most brilliant."
He checked his watch. "I should leave in about an hour or so."
She laughed. "Right. I remember."

She kissed him again, a smile on her face. "Perfect plan, right?"
"We don't count that."

"Good," she replied, a grin crossing her face. She sat up and put her hair back, leaning over him to give him a kiss. "I appreciate it."
"Well," he murmured, "do you think he's right?"
She smiled slightly, turning to look at him. "Apparently."
