Say something good first, and then say something that will make the other person happy. When you meet a sick friend, you can ask him if he is better first. This is a concern for his friend, which will make him feel warm and then say something that will make him happy. For example, you can say that if you are sick, you should refuel and lose weight. This is a weight loss plan for you. This is a humorous teasing behavior, and friends will feel very happy after listening.
