I wish to have some serious conversation with you. . . I have had ten thousand doubts within myself, whether or not I should discover myself to you; but every argument against it has its foundation in pride. I am sure you will hold yourself bound to let no one living know of this application, or of my visit, till I release you from the obligation. . .
PS: Remember that I must be secret, and that the gallery of the House is now so universally attended, that the face of a member of parliament is pretty well known.

–William Wilberforce, as cited in The Life of William Wilberforce by Robert Isaac Wilberforce and Samuel Wilberforce.
