A Deep Sworn Vow
William Butler Yeats (1865-1939), Irish poet/dramatist

Others because you did not keep
That deep-sworn vow have been friends of mine;
Yet always when I look death in the face,
When I clamber to the heights of sleep,
Or when I grow excited with wine,
Suddenly I meet your face.

from The Wild Swans at Coole by William Butler Yeats (1919)
