What I want is to be able to see and feel what another sees and feels. I want to be able to look in the way that another looks - not in the way that I imagine they might look, but in full knowledge. I don't think of stupid petty things here, like how an apple tastes, or what the color blue looks like. I want to know how the world looks to someone who isn't me. And I want to be able to communicate even a small part of how the world looks to me.
You say "you have to be willing to tell someone else everything". This, it seems to me, is not enough. I am perfectly willing to float above the ground weightless, to fly above the treetops in glorious flight. I am willing to be rich beyond imagination. I am willing to communicate anything within myself, to someone who wants to hear it. But this is not enough. No matter how willing I am, gravity still keeps a firm hold. No matter how willing I am, my assets and debts continue to more or less balance. And no matter how willing I am, and even if I found someone who wanted to hear it, I could not communicate who I am and what I see to another. I do not have the words, and I do not believe that either they exist, or that they could.
This is, of course, all predicated on finding someone suitable. Which is, I suppose, what I am waiting for.
