An unexpected yet mesmerizing blog post by Roger Ebert:
The biological reason we fall in love may be to encourage reproduction. Yet why did nature provide homosexuality if that is the only purpose? Why do people marry with no prospects of children? Babies are not the only thing two people can create together. They can create a safe private world. They can create a reality that affirms their values. They can stand for something. They can find someone to laugh with, and confide in. Someone to hold them when they need to be held. A danger of the internet would be if we begin to meet those needs without feeling there has to be another person in the room.
