When someone asks you for your opinion by saying, “A penny for your thoughts?” and you yield to the temptation and put in your two-cents-worth …. What happens to the other penny? Someone said, “It is better to have people think you are a fool than to open your mouth and prove it.” Been there; done that.
The Bible gives excellent advice on the subject of opinions and advice.
A fool takes no pleasure in understanding, but only in expressing his opinion.
Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger;
Next time someone asks for your opinion on a subject, replay these two verses in your mind.
Think about it.
