Tim: How do women and men even stay together?
Wilson: It has to do with barbed wire, Tim.
Tim: [inquisitive grunt]
Wilson: As a boy I used to spend summers at my Uncle Leonard's farm, and at the edge of his property he had a huge oak tree. Running through the middle of that tree was an old barbed-wire fence.
Tim: It went right through the tree?
Wilson: Right through the middle of the tree. When a tree is planted close to a fence, it has nowhere to grow. As it expands and grows bigger, it extends over the fence and slowly envelops the wire. The two separate entities gradually become one.
Tim: Am I the tree or the barbed wire?
Wilson: Well, I don't think you're the tree, Tim. [Tim laughs] Ah, the point is, the two were joined without destroying the tree or losing the integrity of the fence. It's almost as if they belong together.
Tim: Like Jill and me.
