He wanted no sadness attached to his childhood; he loved its memories; any day of it he remembered now seemed flooded by a still, brilliant sunlight. It seemed to him as if a few rays reached into his present; not rays, more like pinpoint spotlights that gave an occasional moment's glitter to his job, to his lonely apartment, to the quiet, scrupulous progression of his existence.

Then he permitted himself to look. (220.127.116.11)
