Where I live isn't the ghetto. The jewelry/makeup standards are about understatement and elegance, as is the no-yelling rule, but you can also find those same jewelry/makeup recommendations in nearly every good fashion magazine. These are largely grownup girl rules, which, rather than being about OCD or worry, have much more to do with good breeding and taste. (Same reasons I don't use the F word to address people on public Internet forums.)
