At least Em, long-suffering as she was, tried to give the child a bit of her heart, which - after all those years of living with Henry on that old gray farm in the middle of the gray prairie - was as dried up as an old pea. She tried, but she wasn't much good at it. It was a bit like trying to water a budding flower in the middle of a dry Kansas summer with a watering can poked through with holes.
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.
