" Aman thinks he scores high with a woman when he does something very big for her, like buying her a new car or taking her on a vacation. He assumes he scores less when he does something small, like opening the car door, buying her a flower, or giving her a hug. Based on this kind of score keeping, he believes he will fulfill her best by focusing his time, energy, and attention into doing something large for her. This formula, however, doesn’t work because women keep score differently. "
