Dr. David Clarke says most guys are clams. Clams bury themselves in the sand and are quite content to hide there. Guys like to hide relationally. They’re naturally much better at tasks that require strength, confidence, and leadership. Those are key skills in business and sports, but they’re not especially useful when it comes to a relationship with a woman.
Women want closeness – connection, understanding, openness, and intimacy. That’s why when a woman’s husband clams up and hides, she tries to pry him open.
