Dear Doghouse Ag2,
Make V-Day happen early, like Monday night. Pick a theme she might like, such as "Valentine's in Venice." Take her to a romantic Italian restaurant, after all, they are 6-9 hours ahead of us in Italy, depending on which time zone you are in. So when you have dinner at seven on Monday night, it's actually Valentine's day in Venice. Besides, the baby sitters are more available on Monday.
Oh, and keep the flowers coming for Tuesday, they will be more of a surprise after the Monday Tuesday.
*We now return you to your regularly scheduled marital professional*
(which I'm sure has a recommendation on what to do after dinner!)
