A student asks a 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
to pick."
The student went to the field, go through 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...."
