Famous quotes containing the word letter:
“Your letter of excuses has arrived. I receive the letter but do not admit the excuses except in courtesy, as when a man treads on your toes and begs your pardon—the pardon is granted, but the joint aches, especially if there is a corn upon it.”
—George Gordon Noel Byron (1788–1824)
