One warm, spring day a Fox was chasing a mouse through the orchard, till the mouse scrambled up a vine with a yet unripened bunch of grapes hanging from it. The mouse peered down at the Fox and Fox stared intently at the mouse. The frighten mouse scrambled over the bunch of grapes, which caused one of the grapes to fall to the ground. The Fox, distracted by the grape, let the mouse escape. The fox dreamt of this moment and scooped the grape into his mouth and chewed. Quickly he spat out the sour grape, proclaiming to himself, “ Just as I thought, they are sour!” But it was still only spring.
Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.
