Adult?

There are moments in my life where I feel a little bit of a disconnect. Today was one of those days. Here I was, sitting in a meeting, spouting off opinions that people were actually listening to and while I'm having this conversation out loud, I couldn't help but think, "I'm an adult. I'm really having this conversation." I don't actually think of myself as an adult most of the time; not in the way I perceive "adult". Especially when I'm not in a work environment. I guess my age probably dictates otherwise. I suppose this is exactly what a "disconnect" is, though, right?
