Those things she's eating? Those are boiled peanuts. (or "juicy" peanuts, as they're known in our house.) Boiled for two days with enough salt to preserve a pickup-full of roadkill.
You don't just pick up a love of those like the one she and I share. A love that caused her to run through the house salivating and squealling "wooooo hooooo!" when she discovered what was bubbling away in the big steel pot on the stove.
That's all genetics, baby.
