Taken from forum;
A student asked his teacher, "What is love?"

The teacher said, "To get an answer to your question, go to the wheat field, get the biggest wheat grain, and come back."

But the rule is - "You can go through the field only once and cannot turn back to pick."

The student went to the field, gone through the first row, and saw one big wheat grain. But he wondered.... may be there is a bigger one else where.

Then he saw a bigger one. But may be there is a still bigger one waiting....

Later, when he finished more than half of the wheat field, he realized that the wheat grains there are not as big as the previous one. He realized that he has missed the biggest one.

So, he ended up the search and went back empty hand. The teacher told him, "That is love! If you keep looking for a better one, you could have missed the right person!"

"What is Friendship then?" the student asked.

The teacher said, "In order to answer that question, go to the same field and choose the wheat that appears nice to you. The rule is is the same."

The student went to the field. This time he is very careful. As he started scanning the field, he has picked many grains that suited his taste and come back to the teacher.

The teacher told him, "You looked for one that is just nice for you, and did not look for the best. That is Friendship".
