A marriage, or a marriage partner, may be compared to a great tree growing right up through the center of one's living room. It is something that is just there, and it is huge, and everything has been built around it, and wherever one happens to be going--to the fridge, to bed, to the bathroom, or out the front door--the tree has to be taken into account. It cannot be gone through; it must respectfully be gone around. It is somehow bigger and stronger than oneself. True, it could be chopped down, but not without tearing the house apart. And certainly it is beautiful, unique, exotic; but also, let's face it, it is at times an enormous inconvenience.
