Life’s under no obligation to give us what we expect.
Margaret Mitchell
Much like Baden Powell and the Boy Scouts promote, always be prepared especially when dealing with others. Although one might think they know what to expect it is often times something else causing the issue or concern.
It is important to remember that to find common ground in your communication to ensure you are able to explain the idea you are trying to present. This may mean reducing your vocabulary to more common, every-day words and phrases or being more precise in the technical description of the problem at hand. Each instance will be based on the overall context of the conversation.
Do not expect everyone will be able to immediately understand what you are saying, and in the same vein, you should not always expect to be immediately understood. Sometimes the communication gap needs to be bridged otherwise you might have the gist of the idea get lost in translation.
Always take the time to understand what is expected rather than simply moving forward believing you know, without doubt, those expectations.
