There's a tendency to do 'throat clearing' in writing. Those opening paragraphs that waffle on before the story really gets going in paragraph 3. The characters who start every speech with Well, or Oh, or Hmm. It's natural, because that's the way we are in real life. We come at situations sideways, clearing our throats before we get on to the nitty gritty.
Trouble is, it's boring to read. Write it in the first draft - first drafts you're allowed to do as much throat clearing as you like - but don't forget to delete in the next draft. You want your writing to be as easy to read as possible. That's only good manners.
