from Difficult Loves

Everything was so beautiful: sharp bends in the path and high, curling eucalyptus leaves and patches of sky. But there was always the worrying thought that it was not *their garden*, and that they* might be chased away any moment. Yet not a sound could be heard. A flight of chattering sparrows rose from a clump of arbutus at a turn in the path. Then all was silent again… Everything in the *garden was like that: lovely but impossible to enjoy properly, with that worrying feeling inside that they were only there through an odd stroke of luck, and the fear that they'd soon have to give an account of themselves.
