What should I say when I call my boyfriend's father?

For a male father, you can talk to him about his career troubles. In the process of telling you, it is equivalent to sharing some unhappiness with you. You said his father was ill. The content of your phone call must focus on his poor health, ask him to rest, and don't be too tired. I wish him recovery. For example, you can say, "Hello, uncle, I heard that you have been in a little bad health recently. You must be too busy and tired at work. Work is important, but health is more important ~ health is the capital of revolution, so you must pay attention to your health and hope your uncle will recover soon ~ "So his father must think you are a smart and sensible girl.
