Circumstances over which I have no control.
Notes from Wikiquote
I hope you will not think I am deficient in feeling toward you, or that I am wanting in desire to serve you, because the results of my attempts have failed, owing to circumstances over which I have no control. | As quoted in The Life and Letters of Lady Hester Stanhope (1914) edited by Catherine Lucy Wilhelmina Powlett, Duchess of Cleveland
