I've never had a girlfriend who cared for gifts on Valentine's Day. Seriously. Many of my girlfriends have been foreigners and the day is about spending time with those close to you. For most, that is with their spouse or those with whom they're involved but it doesn't necessarily mean getting a gift for the person. A card and flowers are a nice touch but the real constant is dinner. You better take her out or cook something special yourself. That's it.
