“Excellent speech becometh not a fool: much less do lying lips a prince.”
Always speak the truth and you will not be made a fool of. The truth is always the easiest thing to remember. When someone ask you a question that you don’t know the answer to, then say you don’t know. If you can point them in the correct direction to who or what may have the knowledge, then do that.
We are known for what we say in life. There are times we can kid around and there are times to be serious. If all we do is kid around and poke fun, then that is what we will be known for.
