What is a one-sentence summary of the following article?
When your friend or family member expresses delusional thoughts, listen to them, but don’t argue. The delusion seems completely real to them, so you won’t be able to talk them into believing something else. Arguing can even make the situation worse, since it will make the person feel like no one understands them. Focus on understanding how the person is feeling. Show empathy for their emotions, but don’t say anything that will reinforce their delusion.  For instance, if your friend tells you that kidnappers are following her, don’t play along. Instead, say something like, “That sounds really scary, but I’ll make sure you’re safe.” Without trying to change the person’s mind, let them know that you aren’t perceiving what they are. For instance, say, “No, I didn’t see any people following us.” See if you can get the person to tell you more about their fears. This can help you figure out where the delusion is coming from and give you a better idea of how to reassure the person. The person may also feel better after talking to you. Ask an open-ended question like, “Why do you think the kidnappers are following you?” or “Do you want to tell me more?” If something in the environment is frightening them, take the person somewhere else. Offer them some food or water. Reassure them that you are not afraid, and tell them you’ll make sure nothing bad happens to them.  For instance, if you’re in a building with a family member who thinks someone is sending them messages over the PA system, take them outside. If the person takes medication, ask them when they last took a dose. If it was longer ago than the bottle instructs, make sure they take a dose as soon as possible.

Summary:
Avoid arguing with the person. Avoid affirming the person’s paranoia. Ask questions. Help the person feel safer and more comfortable.
