Famous quotes containing the word unusual:
“Life is extraordinarily suave and sweet with certain natural, witty, affectionate people who have unusual distinction and are capable of every vice, but who make a display of none in public and about whom no one can affirm they have a single one. There is something supple and secret about them. Besides, their perversity gives spice to their most innocent occupations, such as taking a walk in the garden at night.”
—Marcel Proust (1871–1922)
