What do I want to be when I grow up?

My youngest just asked me, "Mom, what do you want to be when you grow up?" Funny, most questions can be answered with a flippant, no, yes, we'll see, maybe or NOT ON YOUR LIFE! but this one caught me off guard, for several reasons. Was I not already grown up? Wasn't I already 'something?'

What or who am I? To the two short people in my life I'm simply Mom. Not a fancy title for sure, but on a good day, the best job in the world. To my colleagues, I am a teacher, and this is an incredible privilege. To my husband I am many things, all at once. But, if I could choose again, what would I be?

There are so many possibilities: Antique dealer, gift store owner, tea room proprietor,

Hmmm, I guess I can explore the question of what I'll be when I grow up, when I grow up....if I grow up....should I grow up?
