I have found that, when drafting fiction, I tend to omit commas between the clauses of a compound sentence far more often than in my non-fiction writing. I think it is because of flow -- commas interrupt the feeling of natural connection, especially when I'm writing about a character's perceptions or thoughts. For example, I just saw this sentence in my work:
He could tell she didn't like having all the investigative work described as hers, but she had put herself into the spokesperson role and he could use that.
Having been sensitized to this tendency by prior editing, I noticed that, technically, there should be a comma before "and." However, there is also the exception to the rule for short sentences. That's not a short sentence, but the second part could be a short, stand-alone compound sentence. So, what do others think?
1. Absolutely, positively must have a comma.
2. Ehh, it's a judgment call.
3. Commas are disruptive little buggers and should be omitted wherever possible.
