The single biggest problem with communication is the illusion that it has taken place. (George Bernhard Shaw, 19th-20th centuries Irish playwright)
It happens way too often, doesn’t it? We leave someone, thinking we have communicated our expectations clearly, only to find out later that we weren’t understood at all. We must really make sure that what we want someone to remember is actually heard and understood. Repetition and follow-up questions might ensure that we have been heard aright.
Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up . . . that it may benefit those who listen (Ephesians 4:29).
