I'm very lax with my peeps if the rules given above are typical. When they are kids, especially, they are allowed to do pretty much as they like. Hey, childhood is the time for fun! About they only rule for them is NO DRAWING ON THE WALLS! However, kids should expect to be interrupted without warning to pick up trash, pull weeds, and so on.

The teenagers seem to be a pretty serious bunch generally, and already tend to spend a good proportion of their time helping with chores or studying. They are allowed pretty well what time off they like for surfing the Internet, playing games, or watching TV.

In general, adults should remember that work comes first. They should expect to spend most of their time working, even if it means ignoring some of the chores. Since nursing mothers can't work, they should expect to be asked to tidy the house, pick up collectibles, and so on, like the kids. Once a peep gets to Master in their profession they no longer need to work unless they want to.
