Joke teaching plan in logical thinking

I'll teach you another one. Say this to the girl you like: Let's play a game. The rules are as follows: each of us says a word, and then let the other side judge whether it is true or not. For example, if I say something that you think is true, then I lose; If you think this statement is wrong, then you lose. Losers must unconditionally meet the requirements of winners. The average girl won't refuse to play this game. You can let her say it first (you have to understand the rules of the game yourself), and then the point comes. You can say this sentence: "You are my girlfriend." The other party was cheated at this time. If she thinks this sentence is true, then there is nothing to say, and your purpose has been achieved. If she thinks it is false, then according to the rules, she loses. To meet one of your requirements, you can ask her to be your girlfriend at this time ... do you understand?
