There are some things you never let out of your sight. A snake is one. A snake is not likely to hurt you if you have it under your control. But the moment it is free, you are in danger.
Likewise, a person who loves to babble is a loose canon. His words may sound innocuous enough in the beginning, but at the most unlikely moment, he might utter words that bring you and others much harm. Words can be far more venomous than a snake’s bite. For words can penetrate to the depths of our soul. Be careful in entering discussions with those who are careless and voluminous with their words. For the discussion can turn dangerous at a moment you least expect.
Likewise, be cautious with your own words. You may not have intended to hurt someone else, but with many words, harm is inevitable.
