Quarrel in Old Age William Butler Yeats

Where had her sweetness gone?
What fanatics invent
In this blind bitter town,
Fantasy or incident
Not worth thinking of,
put her in a rage.
I had forgiven enough
That had forgiven old age.
All lives that has lived;
So much is certain;
Old sages were not deceived:
Somewhere beyond the curtain
Of distorting days
Lives that lonely thing
That shone before these eyes
Targeted, trod like Spring.
