The course of true love never did run smooth. Once a lover, always a lover. Love is a little sighing and a little lying. Love at first sight is cured by second look. First love, last love, best love.
Blind love mistakes a harelip for a dimple.
He who forces love where none is found remains a fool the whole year round. Love'em and leave'em. You haven't lived if you haven't loved. Love your neighbor as yourself. All is fair in love and war.
