'If music be the food of love, play on.' 'Good night, good night! Parting is such sweet sorrow, that I shall say good night till it be morrow.' 'Love is a smoke made with the fume of sighs.' 'I must be cruel, only to be kind.' 'There is nothing either good or bad, but thinking makes it so.' 'To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man.'
