he teacher said, "in order to answer your question, go to the corn field and choose the biggest corn and come back. But the rule is: you can go through them only once and cannot turn back to pick."
The student went to the corn field, this time he is careful not to repeat the previous mistake, when he reach the middle of the field, he has picked one medium corn that he feel satisfy, and come back to the teacher.
The teacher told him, "This time you bring back a corn.... You look for one that is just nice, and you have faith and believe this is the best one you get.... This is marriage.
