A woman makes a list of things she needs and then goes out to the store and buys these things. A man waits till the only items left in his fridge are half a lime and a beer. Then he goes grocery shopping. He buys everything that looks good. By the time a man reaches the checkout counter, his cart is packed tighter than the Clampett's car on Beverly Hillbillies.
Women love cats.
Men say they love cats, but when women aren't looking, men kick cats. A woman knows all about her children. She knows about dentist appointments and soccer games and romances and best friends and favorite foods and secret fears and hopes and dreams. A man is vaguely aware of some short people living in the house. Men think David Letterman is the funniest man on the face of the Earth.
