Age

How is it that the people I went to school with look so much different, so much older, yet I still look basically the same as I did in high school? Is it the world we chose to live in? Mine of my heart and mind and soul, theirs' of society's designated role? Is it because they've taken more responsibility (real, actual responsibility) and I have not? Am I the child, or are they? Or all of us, or none of us... This is such a complicated question and I don't really feel the desire to delve today. Someday.
