The faculty of speech: a gift or a curse of homo sapiens? The word can kill, or it can just go unnoticed. Chatter is coughing up from an insatiable mouth and clings to the irritated ear of the listener like mucus. On the other hand lucid speech is pleasing to the ear and it allows you to make articulate sounds. The loudness of the spoken words is often inversely proportional to the amount of meaning in them.
The ability to ignore helps, but not for long, because a social beeing is obliged to follow the rules of a noisy society in order to feel the pulse of the modern world. But you can try to calibrate the distance between you and different people. People who speak.
