<human>: Give me the gist of the text in a nutshell

My 10 year-old nephew will stay with my husband and I for 4 weeks while his mom recovers from surgery.  We have an 11 year-old daughter.

There are a number or rules that differ between our households:

* Our daughter gives us her cell phone at 8 PM each night and gets it back in the morning.  My nephew has no such restrictions.
* Our daughter is allowed to use a computer only when an adult is around and gives her permission; we type in the password for her. My nephew has his own laptop and is allowed to use it whenever he wants.
* You have to eat most of your dinner to enjoy dessert at our house. If you don't like something being served you can substitute it with an alternative.  For example, our daughter doesn't like asparagus. She usually chooses baby carrots instead.  My nephew has no food restrictions.  He can eat none of us dinner and three servings of dessert if he wants.
* Our daughter must spend an hour on schoolwork (doing homework or studying) after school. My nephew usually goes straight to video games when he gets home.
* My daughter asks before watching PG-13 movies.  We sometimes allow her to watch rated R movies IF we are watching it as a family so that we can explain things and know exactly what she's being exposed to. My nephew gets to watch whatever he wants on Netflix and plays some M-rated video games that we don't approve of.

Is it reasonable to expect my nephew to follow all of these rules?  My sister has said she disagrees with some of our rules and does not want him to have to follow them.  For example, she doesn't want us taking his cell phone overnight.

We feel that if he's staying under our roof, he should follow our rules - especially since we have a daughter of about the same age and it doesn't seem fair to us that she would have to follow rules and he wouldn't.

Should he follow the rules we have in our household? Or what his mom wants? Or some compromise?
<bot>: My nephew is staying with us. Should he follow the same rules he has at home, as his mother wants, or is it fair that we expect him to follow our rules, which are arguably more strict?
