what's the difference about love and marrige
写篇对话,

one day,plato asked his teacher,"what is love?how can i find it?"
　　his teacher answered:"there is a vast wheat field in front. walk forward without turning back,and picl only one stalk. if you find the most magnigicen stalk,then you have found love."
　　plato walked forwaed ,and a long time passed before he returned with empty hands,having picked nothing.
　　his teacher asked,"why did you not pick any stalk?'
　　plato answered:"because i could only pick once, and yet i could not turn back,i did find the most magnificen stalk,but did not know if there were any better ones ahead,so i did not pick it .as i walked further, the stalks that i saw were not as good as the earlier one, so i did not pick any in the end."
　　his teacher then said:"and that is love."
　　one another day, plaot asked his teacher,"what is marriage?how can i find it?
　　his teacher answered,"there is a thriving forest in front.walk forward withour turning back,and chop down only one tree. if you find the tallest tree,then you found marriage."
　　plato walked forward, and before long,he returned with a tree. the tree wsa not thriving and it was not tall either.it was only an ordinary tree.
　　his teacher asked:"why did you chop down such an ordinary tree?"
　　plato answered:"because of my previous experience. i had walked through the field, but returned with empty hands.this time, i saw this tree, and i felt that it was not bad. so i chopped it down and brough it back. i did not want to miss the opportunity."
　　his teacher then said:"and that is marriage. you see son, love is the most beautiful thing to happen to a person, it's an opportunity but you don't realize its worth when you have it but only when ir's gone like the field of stalks. Marriage is like the tree you chopped. it's a compromise, you pick the first best thing you see and learn to live a happy life with it."
