I hold my hand up, I am awful at grammar. I know the basics, but Microsoft word likes to rub my face in my won mistakes repeatedly. When I check over any of my work I always get that "incomplete sentence." error. With fiction, especially if you are writing a dramatic scene, is the structure of a sentence really that important. Example being, according to the illustrious Microsoft word simply putting: She Ran. Sets off the grammar alarm bells. Also, passive and active voice... Is passive voice really that bad? It confuses me.
