Linked to this is the need for us to be tolerant of what is said to us in the heat of the moment. Conversation entails certain commitments. For it to work, we have to trust in the others involved. When they say they will do something, for example, then we tend to have to take it at face value. At a minimum we have to be open to the possible truth of their words.
Conversation involves interpretation - and in filling the gaps .
To make sense of what others are saying we often have to make leaps forward. People cannot give us all the information we need right at the start. We put their words in context, make assumptions, and add in material to give shape to what they are saying. In other words, conversations often involve people drawing on a large amount of 'background knowledge'. If we do not have it then we have to make great leaps of imagination and hope that all will become clear as the person speaks, or we ask questions.
