Once, long ago, there was a man who traveled from Persia to India on foot. He had       been to India before. When he arrived at a village, he happened upon a fruit stand. In that village, fruit was quite       because of the lack of water. The man was looking around at the fruits when he      a big basket of some very red, very long fruit. It was the cheapest fruit in the shop, not expensive at all.
     the man walked up to the counter (柜台) and asked: “How       per kilo?” And the shopkeeper said: “Two rupees.” Two rupees in India is      . The man thought to himself: “What a       !” So he bought a whole kilogram of the fruit and began to       it. But after he tried a few pieces, he screamed: “Oh, my God!” His eyes watered, his mouth burned, and his face turned        . He coughed and choked and gasped for breath.
But despite his       , he continued to stuff the fruits into his mouth! Onlookers       their heads and laughed. One man yelled: “You’re       , man! Those are chilies! People use them as a condiment (佐料). You don’t just eat them by the handful like that; they’re not fruit!” But the man replied: “No, I can’t       ! I paid money for them, and now I’ll eat them. It’s my money!”
You probably think this man was pretty      , right? Nevertheless, I bet you or someone you know makes the same       on a daily basis. People invest money, time and effort into a relationship, business or job. Even when experience tells them that it’s not      , and they know there’s little hope of improvement, they still        because they don’t want to waste the previous investment. But this is       . It is no different than being the man who continued eating chilies because he didn’t want to waste the money he’d paid for them.
Losing something is difficult, but it is important to        the loss and move on.     you’ll just keep burning your mouth on hot chilies.
