Good Luck?... Bad Luck?... Who Knows!

 A farmer in China had one horse and one able bodied son. The son used the horse to plough the field, which was their only source of income. One day, the horse ran away. All the villagers came to sympathize with the farmer’s ill fortune. “Bad Luck”, said all villagers. The farmer replied, “Good luck, bad luck, who knows”
The villagers walked away perplexed. After a couple of days, the horse came back on its own, with a mate. Now, the farmer had two horses he could use. The villagers came to the farmer to congratulate him. “Good Luck”, they said. Again, his answer was “Good luck, bad luck, who knows”
This new horse was wild. While training it, the farmer’s son fell and hurt himself, fracturing his arm and leg. He was unable to till the land. “Bad luck” said all the villagers immediately. The farmer again said “Good luck, bad luck, who knows”
 A few months later, the Chinese king sent his soldiers to take all able bodied men compulsorily into his army. The only one spared was the farmer’s son. Again the farmer said, “Good luck, bad luck, who knows”
