Have you ever been with a girl, you had an argument and you wanted to make up with her? As long as you say nothing, you can make up with her. If you say something, it's going to be another argument, you are going to get no pussy and you go to bed mad. But if you don't say nothing, it gets closer and closer, y'all make love and it's all expressed through love.
