Glenn Geher & Scott Barry Kaufman

[W]e know what kinds of physical and psychological features make someone attractive to others. It’s often the case that someone is attracted to someone else because of some such specific feature (e.g., smooth skin) without realizing the cause of the attraction. Then you could see courtship, dating, and the development of a long-term relationship forming—all because one member of the couple had smooth skin when they first met and this feature was attractive enough to spark the courtship process. When asked years later about how the relationship began, the smooth skin when they first met may well be the kind of detail that gets lost in the retelling.
