A student ask a teacher, “what is love?”
The teacher said, “in order to answer your question, go to the padi field and choose the biggest padi and come back  But the rule is: you can go throught them only once and cannot turn back to pick.”

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

But may be there is a even bigger one waiting for him. Later, when he finished more than half of the padi field, he start to realise that the padi is not as big as the previous one he saw, he know he has missed the biggest one, and he regreted.

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 realise, you have already miss the person… .”
