As in: undomesticated. Unafraid. In touch with the rhythms of the natural world. Unpredictable. Unruly. Passionate. Beyond normal or conventional bounds. Deviating from the expected course. And even as in playing cards: able to represent any card designated by the holder.
Wild is NOT ditching the kids or running away to join the circus or being an unfaithful wife.
Wild is spontaneous adventures, messy hair, skinny dipping, staying up late, live music, laughing so loud that everyone turns to look, tight jeans, unapologetic luxurious midday naps, venison cooked rare and salmon with the bones, standing up for the kids whether it's polite or not, a sexy marriage, more eyeliner than is really appropriate at school pickup, saying no, getting a babysitter, telling the truth, whiskey in the bath, kissing in public, dirt under your nails. Wild is being the holder of the cards. Wild is designating what the card you hold is worth.
