Romantic chemistry takes many forms. Mood, atmosphere, interpersonal attraction, and other natural forces can work to your advantage when building a love relationship. When you think of chemistry, you may recall that tough class you took in high school or college or envision the chemicals used in science labs. That's not we're talking about here. Chemistry consists of everything that alerts you to the idea that someone is interested. It may be found in that small whiff of fragrance as the person walks by. It may be the unmistakable feeling that you've found someone you “click” with. Chemistry is the right combination of entertainment and intimacy that makes for a great night together. In other words, it's a vast array of input that creates the impression that things are just right.
