" I’ve been kissed by men who did a very good job. But they don’t give kissing their whole attention. They can’t. No matter how hard they try parts of their minds are on something else. Missing the last bus—or their chances of making the gal—or their own techniques in kissing—or maybe worry about jobs, or money, or will husband or papa or the neighbors catch on. Mike doesn’t have technique . . . but when Mike kisses you he isn’t doing anything else. You’re his whole universe . . . and the moment is eternal because he doesn’t have any plans and isn’t going anywhere. Just kissing you. "
