premise: I ' m living a version of a life that I never thought I would , a life that most that I know have n't lived . I ' ve been brave and I am brave and I ' m living in an enormous city and finding it ... well on a good day , fabulous . I realize that I ' m 25 and I really have nothing concrete to show for it . Why does the writer say they are 25 and have nothing concrete to show for it ?
hypothesis: Because the writer has been brave and they are brave .
