In "The Emerald Circus," the character Em exemplifies the struggle of nurturing while feeling emotionally parched. Living with Henry on a barren farm has drained her emotional resources, leaving her heart almost barren, akin to an old pea. Despite her efforts to connect with the child, Em’s ability to provide the love and care needed is limited by her own diminished capacity for emotional expression.

Em's attempts to nurture are likened to trying to water a flower with a faulty watering can, symbolizing the futility of her efforts. The environment around her is harsh, mirroring her internal state, and this makes it difficult for her to give the child the affection they deserve. Through this imagery, the text poignantly illustrates the deep emotional ramifications of a life lived in desolation.
