People talk—A LOT. They can’t stop talking. Talking, getting something off your mind and out there feels good. Talking takes the pressure off one’s mind; our mouths are like relief valves for our heads. The problem has always been that people blurt out whatever is on their mind and say things that often get them in trouble. And yes, I’ve done it too.
