When did I become a grown up?

Last week some friends from high school got together and can I just say I get a kick out of where we all are now. It is so crazy to look at the people I sang with in choir or attended class with and see them chasing down kids and having real jobs. They probably thought the same about me. I feel like I blinked and suddenly we are 10 years older. Question - When did I become a grown up? I realized as I looked around the group that we are not in high school anymore, but man, did I have a blast! Thanks for all the fabulous memories, folks! It was so good to see you guys again!
