Okay, so I'm writing a fantasy novel where the main characters' mother dies right at the beginning. It's not really integral to the story, but it's more of a way to bring the brother and sister together for a moment. I don't want to deal too much with the grief, since it's not what the story is about. So how do I sort of blow it off yet not make them look heartless? It's there a way to do that or should I try to rewrite it so there is no mother? (Maybe she died years ago or something). Also, the father died a long time ago.
