So, Ray, you don't think there's anything suggestive to the fact that everyone with a family or meaningful fulfilling romance is telling you to come clean, while only the chronic maladjusted bachelors who can't make it work with women to save their lives and restrict their romantic behavior to each other during lonely nights at the Fortress of Solitude are pushing you to keep it to yourself, do you? (Also worthy of note, that Bruce and Clark have known each other's secrets for years and wouldn't dream of not having that ultimate sign of trust in each other.)
This is why I like the Bronze Age. Comics actually started to grow up. (Does that make the Modern Age/Crossover Age/Rape Age a midlife crisis or just an extended adolescence after a couple unusually impressive years of preteen maturity?)
