It is an interesting phrase used to describe one of life's most compelling and precarious state of events. Romantic love is the door to relationships, the glue that binds the species together. It involves passion as well as the feeling of safety. This mysterious process eventually happens to almost everyone and is the perennial topic of endless discussion and speculation. It is a fall because we are at least momentarily out of control, disarmed and even sometimes blinded by hormones.
Courtship is a time of affirming all that is attractive and desirable.
Blemishes are elaborately concealed. Cheeks and lips and other erogenous zones become flushed with color and we are swept away by a torrent of events that are the pre-cursor to some of our most elaborate of our rituals. Then things begin to change. The change is usually for the better and almost always permanent. What the movies and the romance novels really don't tell you is that on the other side of that sunset, the next day, life together begins.
