Most people don't learn anything by listening to themselves talk. Chewing your words and presenting them in a way to make them easier to be accepted by others is a very dusty idea.
James 1:20 says that every man should be swift to hear, slow to speak, slow to wrath. I don't take those for idle words. It shows a patience factor to be able to listen and then actually think about the response.
I don't consider this slow to speak trait as unintelligent or uneducated. I consider it to be quite the opposite.
You never have a chance to pray about a situation, or check with the guide for this world and life, the Bible, if you got too anxious about replying. Almost universally when I stop to think about a statement or question posed to me people take it negatively if I don't respond right away. Typically speedy response is reguarded as the real answer whether good or bad response. A slow thoughtout answer is looked at as a lie whether its the answer expected or not.
Somehow we've gotten into this habit of trying to read between the lines, trying to figure out what someone really means, etc.
I would really love to see people get back to posing a statement or question and allowing the responder to think for a moment and then listen to the response and actually just accept what the answer is without trying to figure out what they "really" mean.
