Being human
One of the more interesting features of us hoomans which makes us humans I suppose is our ability to communicate.
Of course there are other species that communicate, but none so intricate and complex as ours is.
Talking <> Communication
So let's get one thing clear, talking is not the same as communicating. Mute people cannot talk yet communicate quite successfully using sign language. If you do not know sign language both parties can talk, but not communicate.
Talking is also not the same as saying things. You can say a lot using your body, tone and other non verbal aspects.
Talking is easy, communication is difficult and sometimes downright impossible. You need two receivers, two transmitters and the necessary equipment to process the signals and boost the quality.
It turns out everyone has a sort of base model receiver/transmitter but customized it so thoroughly that they all send a slightly different signal and therefore it takes tremendous amount of tweaking to make sure you get quality output from the signal.
For some proverbs that run in my family that I quite like that has to do with communication are the following.
Against a traitor you cannot lock your door
Meaning people who lie, cheat, misinform and/or mislead you there are no physical things you can undertake that will help you protect yourself. For example against a burglar you might close / lock your door.
Another one's books are difficult to read
Meaning you do not know what goes on in someone else's headspace. So ask for it.
You cannot battle figments of the imagination
If someone thinks something has happened a certain way and refuses to listen to new information you have a broken signal processor and therefore communication is impossible.
