Symbolism with oranges!

An extract from page 199 of Letters from the Mountains

"Each morning Ernesto lay in bed listening for the distant clatter of her bicycle, the wheels rolling unevenly over the cobbles, approaching his building, coming closer. He lay there letting the vibrations of her journey pass through him and when she reached his window, he opened it and there she was. ‘And here am I,’ he said. How quickly his devotion had emerged and how quickly it had grown. Before, her bicycle had been no more than a soundtrack to his mornings, a rickety rise-and-fall routine that had faded with the preoccupations of the day. Now though, like those oranges suddenly appearing on the trees outside, her image had emerged as if from nowhere, demanding his attention and capturing his heart. Her wavy blonde hair, her broad shoulders, her slim waist, and the dress that flew up as she rode along the uneven street revealing her pale athletic legs, were all so irresistible that he watched her each morning and kept the image fresh by dreaming about her for the rest of the day."
