I think you are right @denmarkguy actually most of the times communication can be very difficult both to the listeners and to the communicators like sometimes we see ourselves you know trying to communicate with some other person and them misunderstanding or misinterpreting what you are trying to express. Actually it's good sometimes you voice out your thoughts in order to know whether it's tallies with what the communicator is trying to explain or express.
But there are also situations where someone will say something and mean something else while the person he/she is trying to communicate with will understand another thing altogether so everything is just; communication.
Honestly, communication it's not just a small miracle, it's a very big one because most times even in relationships you find out that communication is very crucial and then the way your partner interprets what you have said is another thing altogether, so it's all just Grace that we speak and it's been interpreted in the right way and sometimes in the wrong way and then when in the wrong way you just need to go through a lot of stress trying to explain what you meant by what you said.
All we have to do is to speak with caution and in the right frame of mind, being mindful of the way we speak not to be misinterpreted by others.
