Sometimes I dream up ideas for stories, books or movies. Generally they would get told to the unlucky grand-kids who happened to be riding in the back seat on a long drive. No one ever writes them down, of course, and they get forgotten. I don’t have the stamina to actually write a full blown story. In this case, I wrote this much down a few years back. Maybe someone else can “make me a movie”.
What if, in the future, when time travel is first being developed, we have a descendant of mine who works in the university environment, either as a professor or researcher. His hobby is genealogy, and he has developed quite a complete and deep family tree. Of course, there are gaps in his tree, which he continues to work on.
