Communication is present even when you deny communication. To say that you do not want to communicate, you have to make a gesture and that gesture is part of communication. Silence is another way of communicating and it depends upon cultures.
If you take a long pause before answering a question, it may be though as a sober gesture in some cultures while in other they may take it as a dumb gesture. This means that communication is not always done with the help of words instead sometimes your body language can tell others lots of things.
For example when you come home late and your mother catches you then, even if she does not say anything but you know from her facial expressions that she means something and that is “grounded”.
Once you speak words then, you cannot bring them back and this property makes all kinds of communication irreversible. That’s why that saying of think before you speak is popular because once you speak then, you will do the damage or take the advantage and you cannot reverse that advantage or damage afterwards.
To avoid any harmful action by your communication, you need to make sure that you are using most positive set of words and sentences because it is another saying that states
“Message will be heard in its most negative sense, if there is any”
This clearly says that you should avoid the use of negative words and expressions in your communication to make it more effective and more positive.
Contextual communication means that you can never communicate in isolation and you always need some kind of link with you to explain your communication to. It can be one of your friends, a social meeting, an organizational meeting, your life partner or anyone else but you got to have someone who should read and respond to your communication.
This makes it even more interesting because when some other party is always involved then, this means, you have to think more about his point of view and communicate accordingly. If you started to communicate in your own way then, you may understand the meaning but you may convey a different meaning.
From all of these properties, one thing is evident that you need to be very precise about your communication and if you added anything wrong in your communication then, it will ruin the whole purpose of communication and you will face some kid of loss.
