'do people ever grow up?' is too loose of a question. depends in what terms you define 'growing up.'
i define growing up as knowing your responsibilities and handling them appropriately. you know how to face challenges in a mature, responsible manner and are capable of making important decesions that will effect you in the long run. you accept responsibility for your actions, right or wrong. you are wise enough to know that you don't know it all and aren't afraid to admit it. you know how to control yourself in almost every situation and don't resort to childish tantrums when you don't get your way or start a fight with everyone that disagrees with you.
there's more i could say, but that's pretty much what i define as being "grown up." if that's what we're basing as the definition of being grown up, then my mother, who is 47, is nowhere near being grown up. that is only one reason i do whatever i can to stay as far away from her as possible.
if growing up means that i can't sometimes have childish juvinile fun (that doesn't get anyone hurt or breaks the law) or just really have "silly" fun and toss all my cares away for a few hours or days or whatever is appropriate and act like i'm a teenager again (in a somewhat mature and law abiding mannter), and i've accepted that my life and career is set for good and i can't change it, then i don't want to grow up. being 40 and talking about what you want to do with your life doesn't mean that you havn't grown up, only realized that your life is far from over and you still have time to enjoy it. when i'm 40, i'm sure i'll be talking about what i want to do with my life. the way i'm looking at things, if i really want to go to law school, i won't be done until i'm probably 32 and i'll be early into my career at 40. also, my son will turn 18 when i'm 41, and by the time i'm 42 he'll either be off at college or just out of my house, it'll be like starting life over again

too bad i'm only 26 and i've got 15 more years to go
