Closure is the process by which we bring a chapter of our life to a close by tidying it up in our heads and allowing our emotions to settle. We make meaning of it, consign it to the past, retain any necessary lessons and give it its appropriate temporal space in our long-term memory. Closure cleans up any outstanding issues and makes space for the invention of a new future, uncontaminated by detritus from the past. Non-closure is when we know that things about a situation are still a bit messy and that there is a possibility of future events hooking into old undesired behavioural patterns. Closure is usually achieved through time passing but quality conversations that facilitates re-examination and alternative meaning making can speed things up and help ensure that useful learning is retained.
