Garrison Keillor has a great quote about marriage:
In general, the rules for marriage are similar to the rules for being in a lifeboat on the open ocean: don't crowd each other, no sudden moves, and keep all disastrous thoughts to yourself.
In searching for it, I found another great quote about the perfect woman:
The perfect woman is the woman who you love to converse with and who you want to tell everything to. The moment you have a big experience, you want her there to listen to your account of it. Her take on things fascinates you, her talk is pleasurable to you, and you love her company. That's what you want in a companion.
Is this true? Do men change at a specific age? The ones in my age range seem to be a lot more shallow. Maybe that's SoCal for you?
