"A bird doesn't sing because it has an answer, it sings because it has a song"
The New Faces
by William Butler Yeats
If you, that have grown old, were the first dead,
Neither catalpa tree nor scented lime
Should hear my living feet, nor would I tread
Where we wrought that shall break the teeth of Time.
Let the new faces play what tricks they will
In the old rooms; night can outbalance day,
Our shadows rove the garden gravel still,
The living seem more shadowy than they.
