I've never seen anyone pick up a sock without my making them do it. Have you? It would be nice to be able to train them to do that. As for the rest, they seem to come "pre-loaded" with a menu of tasks that they do. Just put one to work on their career when they don't want to do that, and you will see a lot of alternate tasks roll out. Also, they start their careers at step one without carrying over any parent's accomplishments into the game, which corresponds pretty much to RL, don't you think?
