I think that it's important to try to keep reality. I think that Gabriel Garcia Marquez speaks a lot about reality in his magical realism. So I don't think we have to be hyper-realistic. But we have to understand the pressures that undergird the lives of the characters within that novel.
... We must remember that there's more than one story and plot in every novel. There are at least as many stories as there are main characters, and each of these stories has to have multiple plots to keep it going - blood and bone, nerve and tissue, forgotten longing and unknown events.
