what is the difference between love & marriage

A student asked to his teacher, "What is love?"The teacher said, "in order to answer your question, go to the wheat field and choose the biggest wheat and come back.

But the rule is: you can go through them only once and cannot turn back for pick."

The student went to the field, go thru first row, he saw one big wheat, but he wonders....may be there is a bigger one later.

Then he saw another bigger one... but may be there is an even bigger one waiting for him.

Later, when he finished more than half of the wheat field, he start to
realize that the wheat is not as big as the previous one he saw, he know he has missed the biggest one, and he regretted.

So, he ended up went back to the teacher with empty hand.

The teacher told him, "...this is love... you keep looking for a better
one, but when later you realize, you have already miss the person...."

"What is marriage then?" the student asked.

The 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."
