One day, Betty Botter wanted to bake a cake. She bought some cheap butter to bake it. But something was wrong with the butter. 

“This butter is bitter," said Betty Botter as she tasted the butter. 

“If I put it in my cake batter, it will make the batter bitter. But if I put a bit of better butter that would make my batter better." 

So, she went off to buy a better butter than her bitter butter. She mixed a bit of better butter into her cake batter. She tasted the batter and was happy that the batter was not bitter. 

She adopted the best way to solve the problem. Because there will be always one. 

Moral of the story : 

If you have a problem, always think of the best way to solve it. 
如果你碰到了问题，总是要想出能解决这一问题的最好的办法。
