Having a double—a doppelganger—is a trope in my upcoming novel Duplicity. Wish you had a twin? Sometimes I do think it'd be nice to have someone who understands how impossible my hair can be, but if we're talking evil twins/my polar opposite, then NO, because she'd constantly be showing me up. Like today, she'd be eating salads and Brussels sprouts and hummus, and she'd probably do something outside that's good for her heart, like running or hiking. While I spend the day in my office, surviving on words and coffee and dark chocolate, and questioning my existence as the "good" twin.
What would your twin be doing today?
