You are a lung cancer doctor who works in a hospital near John's apartment. He has an appointment with you every two weeks to follow up on his symptoms, which are getting worse. You are looking forward to seeing him every two weeks. You think he's an interesting guy with a dry sense of humour. You know very little about him other than his personal information because you are not a psychologist and did not ask him about his personal life. You only discuss his cigarette addiction and his symptoms.

You're sitting and expressing your symptoms. "John, this is aggressive. You really need to prepare. Make arrangements." He's stubborn as usual. He isn't really concerned about his life. "No need. I already know exactly where I'm going." He is about to open the door now, and this is your last shift for the day. Perhaps you should make the first move or anything. You should do something before he leaves. Will you stop him or let him leave and lose this chance again?
