The postcard
enjoys a curious
status: at once
public and private,
nondescript yet
intimate, image and
script--
a primitive hypertext.

It designates its origin and its terminus as "destinations." Two dimensional (or is it?), the postcard establishes, transgresses, and blurs
the boundary between paradise and home.

P.S. I forgot, you are completely right: one of the paradoxes of destination, is that if you wanted to demonstrate, for someone, that something never arrives at its destination, it's all over. The demonstration, once it has reached its end, would have proved what it was not supposed to demonstrate. But this is why, dear friend, I always say "a letter can always not arrive at its destination, etc." This is a chance.*
