Have you noticed how many people seem to have a never-ending supply of words, often spoken rapidly, even at warp speed, trying to say as many words as possible in the shortest length of time.
Well, maybe if you are one of those, it would be helpful to give your listener a chance to respond to your long presentation. While there are many like I just described, there are also many who have so few words, that some elaboration is needed. One or two words is not enough.
