After careful research, I've discovered how they do it. They each own a RALF (Reflective Audio Listening Filter). It's a device they have installed into their ears that reflects their own words and thoughts back them the instant it senses audio that doesn't match the content of the wearer's brain. It's an amazing technology that is packaged so small, you can't even see if someone is wearing one. Oh, but I can give you the indicators of a RALF user:
- If a person asks you a question, but doesn't let you finish your answer; he's got a RALF
- If a person goes glassy-eyed during your conversation until you mention her; she's got a RALF
- If a person can always connect a tragic world event mentioned in a conversation to a not-so-tragic event in his life; he's got a RALF
- If a person can't get through a conversation without talking about herself; she's got a RALF
Sorry, you may not be able to have a RALF installed. It causes a severe allergic reaction in people that actually care more about others than themselves.
