As the AT's evolve they will begin doing thier own chores. I already started this last update with Gina and Becky, and mom not being such a Harpy about the living room.
I don't think they are that bad. Becky was the most abusive, and that's mostly because she was the closest to Nathan before he went to jail, and is suffering from a serious case of teenage angst about the whole thing.
This is important. Having knowledge of a subject, does not mean they are interested in it. I know a lot about c#, but I don't watch the microsoft feeds for new code updates, nor do I try to use every little thing microsoft adds to c#. If I was interested in being a programmer, then I would keep up with that type of stuff. Getting thier skill ranks up is great for when that person is ready to adopt that new interest, but currently, Diane may have read a lot of Game of Thrones, but that doesn't mean she's gonna be cool seeing Nathan rub one out.
