I hate writing filler scenes. I try to have as few of those as possible, but sometimes you just need them to keep the flow and set up for the action.
My least favorite characters to write are the guys' family members. Wives, kids, parents, siblings. As we've already discussed, sometimes it's unavoidable to at least give them a mention, depending on the situation, but I don't like actually making them into characters. I've written a lot of Lauren and Leigh in SAMS and haven't minded them so far, but the more I can make it just about the guys, the better.
