Broad-minded, maybe. Socially active? Try "dropped off the face of the Earth" maybe?
Although, in a way, it's nice to be anonymous. I don't know if it will last long, since I'm living in a fishbowl, but for now, it's okay. I think that part of my invisibility comes from being a mom with kids and no husband anywhere to be seen... most of the people at church or at school won't touch me with the proverbial pole; I'm an unknown quantity and I might be dangerous.
