Actually, reading forward from the comic linked to, I don’t think you ever do it again, so it probably isn’t a big problem, and even before the linked one it only happens about 3 or 4 times.
Still, its a habit i’d like to avoid. Besides, anything to cut down unneeded dialogue is a plus. I guess I do that because when I try to keep it simple someone always says"I don’t get it.". Or at least thats whatI’m afraid of half of the time.
