It's a conversation between husband and wife, and the husband complains that his wife always compares himself to the house next door and asks him to decorate and buy things according to the pattern of their house. The wife replied disapprovingly, "As long as there is something new in the house next door, we will do it."
The husband then told his wife that the latest in the house next door was to marry a young and beautiful wife. The joke implies that the wife is just following the trend and has no real opinions.
The second story takes place on a college campus, where a boy confesses to a girl by a lake, and the girl asks the boy to jump into the lake before agreeing to him. The boy jumped down decisively and swam up covered in mud, and the girl came to try to wipe him, but the boy avoided it and told the girl that he was not interested in her anymore.
This story shows the firmness and decisiveness of the boy, indicating that he has lost interest in the girl. The third story reveals the cruelty and helplessness of real life by contrasting fairy tales and reality. In the fairy tale, after the princess kisses the frog, the frog becomes a prince, and everyone cheers and wishes.
And in reality, the princess kissed the frog but contracted the disease, and the people around her sneered. This story tells us that real life is not as beautiful as a fairy tale, and sometimes we face unsatisfactory and frustrations.
