am i really growing up?

I had a weird moment tonight. I was sitting in my den with my parents watching fireworks on tv and reading a book, and I turn to the side table to take a drink of my Diet Coke and see one of my high school senior pictures. It was a weird moment...I stopped to look at the picture because I just got my haircut yesterday, and I was comparing color and style. But then I looked at young little 18 year old me, and I started thinking about how much has changed since then and everything that has happened. It was a strange feeling. I guess that means I'm growing up?
