Famous quotes containing the word return:
“Live within your means, never be in debt, and by husbanding your money you can always lay it out well. But when you get in debt you become a slave. Therefore I say to you never involve yourself in debt, and become no man’s surety. If your friend is in distress, aid him if you have the means to spare. If he fails to be able to return it, it is only so much lost.”
—Andrew Jackson (1767–1845)
“I find very reasonable the Celtic belief that the souls of our dearly departed are trapped in some inferior being, in an animal, a plant, an inanimate object, indeed lost to us until the day, which for some never arrives, when we find that we pass near the tree, or come to possess the object which is their prison. Then they quiver, call us, and as soon as we have recognized them, the spell is broken. Freed by us, they have vanquished death and return to live with us.”
—Marcel Proust (1871–1922)
“I never saw so sweet a face
As that I stood before:
My heart has left its dwelling-place
And can return no more.”
—John Clare (1793–1864)
