The moment of farewell is always remarkable and significant, as it marks not only a change, but the point of no return, after which the past circumstance, whether very important or not, will live on only in the memory. The usual tears show the awareness of the irreversible, as well as the appreciation of what has been lived. It is beautiful and it is relevant, and it seems that, without such an experience, one never really assimilates the importance of what there was and, perhaps fortunately, will never be again.
