Everything has a size. Even a smile. The deepest smile spreads across the face, puts a twinkle in the eye, and is felt in the stomach. This smile is bigger in size than any other.
Most women derive their happiness from the men in their lives. Men who care deeply, are attractive, and have that magic charm increase the size of their woman's smile.
When people want to know you better in future, they will see the woman sitting next to you and feel the size of their smile. The bigger the size of their smile, probably the bigger is the breath of your heart. It all boils down to the size of a woman's smile.
