When Did That Happen?!

My husband and I are currently in the process of moving into a larger home and readying the first home for sale. We both also have a lot of different changes going on with our jobs. So, as I sit here on a Saturday night (?!) checking and replying to work e-mail (?!), I can't help but ask myself, "When did I become an adult?" It seems to have happened so gradually. But it's so weird because most of the time I still feel like the dorky girl with frizzy hair who always did her homework.
