Infront of him a girl was sitting who was constantly looking at those flowers. The old man noticed this girl and asked her if she like these flowers. The girl told the old man that white lillies ar her favourite flowers. Then the old man told the girl that his wife loves white lillies too and he often take these to her and she gets happy to see her favourite flowers. He told the girl specilly on there aniversary how he used to fill the whole house with these flowers ..
