wishful thinking

Dream --
I see a postman everywhere
Vanishing in thin blue air;
A mammoth letter in his hand,
Postmarked from a foreign land.

The postman's uniform is blue.
The letter is of course from you
And I'd be able to read, I hope,
My own name on the envelope

But he has trouble with this letter
Which constantly grows bigger & bigger
And over and over with a stare,
He vanishes in blue, blue air.

- Elizabeth Bishop, Dream--
