As the years pass, the winters seem darker and colder, the spring unsettling and fickle, and the rays of the summer sun seem wrapped in a distant, leaden cloud that drains them of energy. As the years pass, the flowers are only flowers by name. Their colours and perfumes largely fade. “Here are some flowers for you,” we say one day to please our aged grandmother. She cautiously holds out her hand, for she can barely see the colours or smell their perfume, but, because we used the word “flowers”, she looks at them as if we had presented her with a bunch of fresh memories and bestows on them a faint smile, slightly sad and distant.
