I've decided to be an undecided voter. It's back in vogue. They could build a reality show around me. They could start with a dramatic re-enactment of my childhood. What's your childhood got to do with this? For a long time, I couldn't decide which kid to play with: Brooke, the smart but secretive blond girl who sometimes fibbed ... or Mo, the rich bully who insulted everyone and was in treatment for pathological lying and Twinkie-hoarding. Childhood is full of touch choices.
