Could it be that you always follow the rules, dot your i's and cross your t's, eat all your dinner BEFORE you have desert, say yes and no, please and thank you....and others don't and that frustrates you?
Also, a little more info like an age range (unless you would like to give your age, but like are you a teen, 20's 30's etc) might also be helpful to understand your plight. You sound an awful lot like someone I know.
