What do you mean, you seem to be a nobody to them? Like everybody is running wild? So this is why they have problems and had to move in with you to begin with? So how could you help them change the way they do things now, so they are easier to live with, and have a better chance of continued success. Can you do those house rule & chore charts like they had on the Nanny 911 shows? You may be outnumbered but you are still the boss.
