I used to think I wasn't "grown up" and still do in many ways. I finally recognized last year that it mostly was because I was usually given responsibilies for which I had no training and was always "new boy on the block." Doing well only meant more of the same. My nineteen year old daughter asks for my guidance in some things, but either doesn't think I am grown-up either or is comfortable with zany behavior. I think maybe one is grown up only when one stops growing.
