Intro #2 for contrast

My present self would be so disappointed in the old me. How could I have been so “young and dumb,” as the saying goes? Could just four years in the Army really change a person so much? How could a person of 28 years be considered a man when just six years earlier many would say he was a juvenile? Could a few drill sergeants and a couple combat tours really change a guy so much that he would completely change his view on school, family, and even life itself? I say yes.
