Fond Memories That Could Have Been

This trope is an incredibly painful but nevertheless important Aesop that is appearing with increased frequency in Anime dramas that are centered around parent-child relationships.

The father or mother in question has stayed aloof from their kind and loving child, often Too Good for This Sinful Earth, a victim of a terminal illness or destined to give their lives for the good of humanity. This is usually due to their cowardly refusal to become emotionally attached to someone they don't believe they can hold onto.

Far too often, far too late, do they realize how much they love their child only as they are about to be lost forever.

In desperation to hold onto what could have been, the parent will plead for departing offspring to stay so that they may spend the quality time together that he was too proud and aloof to make, often accompanied by imagined images of happy memories that could have been. This will be made all the more painful by the child forgiving the parent for their mistakes as they Go Out with a Smile.
