A more thorough explanation:

Definition: An intermeddler is a person who interferes in a situation where they are not wanted or needed. They may try to help, but they have no legal obligation to do so and cannot demand anything in return.

Example: If someone sees a car accident and rushes over to help, they are not an intermeddler. However, if they start giving medical advice without being asked or getting in the way of emergency responders, they become an intermeddler.

Explanation: The example illustrates how someone can become an intermeddler by interfering in a situation where they are not needed. In this case, the person is not a medical professional and is not authorized to give medical advice. Their actions could potentially cause harm or delay proper medical treatment.
