Remember the last time someone gave you exactly what you wanted, even before you knew what it was? Let your imagination, or the last wistful conversation the two of you had over coffee, be your guide. Give her a day at the races; a night at the movies; a trip to her favorite museum; a handyman for a day; a personal chef to cook dinner for two; a car detailing, bumper to bumper; a beauty makeover or a closet overhaul; a house call from a personal organizer; a donation to her favorite charity.
