There is no maturity in issues of love. If you've ever seen a woman take an axe to a man's Harley-Davidson, you will know this.
People never grow up. "Adulthood" is a myth. The only difference between children and adults is that our toys cost more, but we still cry and pout and think the world should go our way.
I have seen a father give a lecture to his daughter about being responsible about her homework, to quit eating so much candy, and to go to bed early. Then, he went out, snorted a rail of cocaine, got drunk, and then got locked up for public disorderly conduct after telling a cop to suck his dick.
Out.
