The most classic example of a prank conversation was as follows: A: You're really selfish. You have to fight for what you want. Why wait for others to help you? B: But what I want isn't something that can be obtained by fighting for it selfishly. I have my own reasons and considerations. A: So you're saying that I should ask you to help me fight for what I want? B: No, I mean you should consider the impact of your actions on the people around you instead of only considering your own interests. A: But this doesn't mean that I don't consider my own interests. I'm just thinking about how to better balance the relationship between the two. B: Ah, this is really complicated. However, I still think that a person should learn how to look at himself and the people around him rationally instead of only focusing on his own interests.
