There is an old legend about two little girls who moved to a new house with a garden. The first little girl went out to look at the garden and came back dolefully, saying, “Mother, the garden is a sad place; all the rose bushes have thorns on them.” The second child returned joyfully, saying, “Oh Mother, the garden is a wonderful place; all the thorn bushes have roses on them.”
