1. No Frostbite Spiders inside the house.
2. No Mudcrabs inside the house.
3. For Talos' sake, no skeevers inside the house.
4. If I come home after 10 days of mass murdering some of the most disgusting creatures Tamriel has ever seen I don't want to play tag, hide and seek or anything else, so don't ask for it. That's what we got the housecarl for.
5. You may not use "Elf-ear!" as an insult when my character is an elf.
Other than that, they got pretty cool lives. 1000 gold pocket money when asked, always get a present when asked (first time my girl Sofie asked me for one I gave her a Glass Dagger, lol), they won't ever have to clean the house so the overtrained muscly housecarls can be lazy instead and I don't care when they go to bed. I don't mind late bedtimes, I know how frustrating it can be when you want to watch the final episode of Family Guy but your parents won't let you.
And best of all: no school. You get to learn how to be like a ninja or overpowered mage, but that's it. No math exams etc.
