Plato, a great thinker and philosopher, asked Socrates, the teacher: What is love? Socrates told him to pick the biggest and most golden ear in the whole wheat field first. He could only pick it once, and he could only go forward without turning back.

Plato did as the teacher told him. As a result, he walked out of the wheat field empty-handed. The teacher asked him why he didn't pick it. He said, "You can only pick it once, and you can't look back. Even if you see the biggest and golden one, don't pick it, because I don't know if there is a better one ahead. When I walked to the front, I found it was not as good as what I had seen before. The biggest and golden ear of wheat has been missed, so I didn't pick anything. "

The teacher said, "This is love."

Then one day, Plato asked his teacher Socrates: What is marriage? Socrates told him to go to the forest first and cut down the largest and most lush trees in the whole forest. He can only cut once, he can only go forward, and he can't look back.

Plato did as the teacher said. This time, he brought back an ordinary tree that was not so lush and not too bad. The teacher asked him, "How did you bring back such an ordinary tree?" He said: "With the last experience, when I was halfway to nothing, I saw that the tree was not bad, so I cut it down so as not to bring anything out in the end."

The teacher said, "This is marriage!"
