The Mayor of Casterbridge
How we cite our quotes:
Yet to Elizabeth-Jane it was plain as the tow-pump that Donald and Lucetta were incipient lovers. More than once, in spite of her care, Lucetta had been unable to restrain her glance from flitting across into Farfrae's eyes like a bird to its nest. (26.21)
Elizabeth-Jane can see right through Lucetta, in part because she's in love with Farfrae herself. Hardy is fond of using bird imagery, and this is one instance where the imagery isn't totally depressing: Lucetta's eyes are like birds, and Farfrae's are like a cozy little nest. When their eyes meet, it feels like home to Lucetta. Isn't that a sweet metaphor?
