Many of the points in this article are so important with the way in which we communicate with each other, many of these things we do automatically such as gentle interruptions and what has been studied earlier this week "non-verbal communication'. I few don't use a lot of these ways of communicating when trying to provide information/meaning it is not put across properly and will not be engaging enough for the listeners of this information to understand it in full detail.
