Tergiverser (tare-zhe-vare-say) means “to equivocate” or hesitate among choices. This is a terrific time of the year for those prone to indecision. Fastachi, a gourmet chocolate, nut, and candy emporium is just the sort of place where you might need to hesitate among choices (83 Charles Street, Boston). Would Dad prefer crystallized ginger enrobed in dark chocolate, fruit gums bursting with just-picked flavor, or artful marzipan. Yes. Tergiversez no longer! Buy everything.
