1 - You'll never run out of toilet paper

2 - There will always be some food in the fridge

3 - Unlike your roommates, at least one of you parents will live apparently to clean

4 - Better cable channels, TV and Audio sets !!

5 - There will always be a car at the garage with a full fuel tank

6 - Washing magically done, fresh and wrinkle free clothes

7 - Liquor Cabinet !!

I almost forgot why I really wanna leave! Ahah
