One fire burns out another’s burning,
One pain is lessen’d by another’s anguish.
– William Shakespeare
Romeo and Juliet, Act 1, Scene 2. Benvolio is trying to get the lovesick Romeo to forget about Rosaline, by encouraging him to look at another girl. He uses the image of quenching one metaphorical love fire by starting another. There is irony and foreshadowing here, since Romeo will be replacing his heartbreak pain over the loss of Rosaline by another pain – his doomed love for Juliet.
