I grew up in the fifties, a time when adolescents and young teens spent time together — playing, goofing off, dancing, attempting to philosophize, and observing and drawing interesting conclusions based on those observations. A fun time, a relaxed time, a sharing time. Some of those interesting conclusions about the opposite sex were:
