Plenty of emphasis has been put on the importance of the first impression. Any article talking about human relationships, interviews, important meetings, etc. highlight that the first impression is decisive for the perception we give to the counterpart. Indeed, it is essential as there is no second opportunity to make a first impression.
However, another important moment has often been neglected: the last one. The so called Von Restorff effect is certainly not as widely know as the first impression effect. However, the impact is no less. Hedwig Von Restorff (German physician / psychologist) proved that the last item on a list has a long-lasting effect. Last impressions are thus as memorable as first ones.
A bad end could ruin the great effort put in the first few seconds; it can pale the positive effects of a good beginning. Let it not be so. Beware of the last impression you are leaving people with and end every interaction on a good note.
