It looks like you have a daughter or daughters. Suppose that your daughter dates a mature, well-connected, well-read, well-traveled, patient, caring, considerate gentleman with a refined aesthetic taste who introduces her to his hand-picked social circle, acts as a catalyst of her quickly becoming more sophisticated than she otherwise would be at her age, exposes her to a wide range of experiences that she would not be able to have with an age peer, shares whatever wisdom he has accumulated from making his own mistakes in the past and possibly even helps her avoid making similar mistakes, and does all of that graciously and , without any remnants of adolescent angst or penchant for overly dramatic behaviors... still not good enough for your daughter?

Or, say, she dates a pathetic loser who by age 50 has not really accomplished anything and who latches on to her in a frantic effort to feel better about himself... would your reaction to this kind of a scenario and the scenario above be identical? Or, say, your daughter dates an older man who is a heroine addict and your daughter, god forbid, becomes interested in using heroine via associating with this guy... still same reaction? I highly doubt that. Isn't who the person is that matters, ultimately, and not the person's age?
