My theory is - we don't really go that far into other people, even when we think we do. We hardly ever go in and bring them out. We just stand at the jaws of the cave, and strike a match, and quickly as if anybody's there.
It seems to me that you need a lot of courage, or a lot of something, to enter into others, into other people. We all think that everyone else lives in fortresses, in fastnesses: behind moats, behind sheer walls studded with spikes and broken glass. But in fact we inhabit much punier structures. We are, as it turns out, all jerry-built. Or not even. You can just stick your head under the flap of the tent and crawl right in. If you get the okay.
We are like sculptors, constantly carving out of others the image we long for, need, love or desire, often against reality, against their benefit, and always, in the end, a disappointment, because it does not fit them.
