I am not sure if I get the question, how I get it is what things are a must with my kids? If so here are some (not all) that I think is what you mean
To my 3 year old:
-Use napkins not her clothes
-Not hitting, specially hitting parents, I really don't like when I see this happen.
-When is bedtime it is bedtime, unless she is sick she has to go sleep or at least stay in her bed reading a book but no out.
-Respecting times outs
My 13 year old is really a good kid, lately I have to put more emphasis to some stuff now that she is growing:
-Absolutely no coward talking, I HATE that, I mush rather she talk to me back, which she would more likely get in trouble but the coward talk (the one when they talk softly enough for you not hear what they say but loud enough for you to know they are talking back) that is just NOT allowed at my house.
-No lying, is easy, what ever you do, you may or not get a punish or a talk (depends) but with the lie not only you have double punish but you lost my trust and that to me is the worst thing it can
-Being disrespectful, one of the ones that bother me more about tis one is when the teen are so disrespectful to others "trying" to be "cool".
I also agree about interrupting but also goes two ways, if the kids are talking I don't like when a grown up interrupt them just because they are kids.
Oh my, I am just reading some of the other answers and I agree with so many, many I didn't even notice I do, lol.
EDIT: My 13 year old also don't drink soda, I get a lot of talks for others because of this, I don't even mind my kids to have sweets here and there like ice cream or chocolate, but soda is a no-no at my house.
ADD what Theresa N. said to my list too. sense of humor, love to live things, self esteem and huge grades are important at my home too.
