To speak clearly, to speak with clarity and to speak sincerely, is to be kind. When communications are vague or convoluted, the wrong impressions can be given and the wrong conclusions can be reached.
Saying what you mean and meaning what you say, reduces confusion and uncertainty. Answering the question seems to be difficult for many. Why do people wander all over the place, digressing through segways, never giving an answer which satisfies.
Double meanings might tickle and tease the mind for a while, but as a matter of regular practice it is not sustainable. It is not healthy because simply to understand is a strain.
