"SOME things I never would forgive!""Unpardoned" by Florence Earle Coates. Published in Harper's Weekly (23 March 1912), The Unconquered Air (1912) and Poems (1916) Volume II.
So said you, dear, not knowing
That love is dead unless it live
All charity bestowing.
O you whose heart love so could brim
In cruel need, learn this of him
Whose all to you is owing:
The one wrong man can not forgive
Is the wrong of his own sowing!
