Softly singing

'The conditions of a solitary bird are five.  

The first that it flies to the highest point; the second that it does not suffer for company, not even of its own kind; the third that it aims its beak to the skies; the fourth that it does not have a definite colour; the fifth that it sings very softly.'

Don Juan to Carlos jotted down in a notebook thirty five years ago.  Came back to me today.
