I've always loved having a secret identity.
In high school I loved moving between non-overlapping social circles--starting fullback on the soccer team one day, dark and brooding poetic genius the next (yeah, right...well, our self-image is always a bit off in high school, eh?) In college, I loved being a typical Harding student...while never attending a single devo that I can remember, and never joined a social club. When I was in Oregon, I loved being a Southerner from Tennessee--I played up the accent, called everyone hon, said y'all at every opportunity. Doing my M.A. at ACU, I loved waiting tables at Cypress Street, knowing that even though I was performing a thankless task for an unpredictable boss and a mostly snobbish clientele, I was in reality a super-smart theology student; I could serve tea and coffee, do a tableside flambe dessert of Bananas Foster, all the while contemplating how I would add to the accumulated wisdom of Christian tradition another definitive non-answer to the problem of evil. In China--well, who needs a secret identity there; being an American provides you with enough celebrity mystique to drive you nuts.
Here, I am super-mom by day, academic by night; and somehow--though not enough gets done on either front--being one makes being the other so much more satisfying.
