We have the young, and we have the young at heart.
There are also those of us who are young and stupid, who imply that they are older than they are and on a certain level wish that they really were older. They try to sound wise to cover it up, have trouble telling people what they do for a living, where they live, who they live with, what they do during the day, and what their favorite colors are. They try to sound wise on occasion, they fail and end up appearing younger and more foolish than they might really be. And in the rare instances when they realize that they might fail, they slap some self-irony on it. People like me. I suppose they also generalize to appeal to their conformist side.Don't feel out of place, no one really is.
