Rapport is the presence of trust, harmony, and co-operation between people. A relationship or state of having trust and mutual responsiveness with others. Rapport often occurs naturally, and one of the focuses of NLP is learning how to consciously develop it with someone, quickly and easily. Breaking rapport can also be useful in some circumstances. Rapport can be easily seen when two peoples behaviors match each other. This is often accompanied by an internal sense of mutual liking and understanding.
