Sure there's a St. Valentine, as much as there is a St. Nikolaus (Santa Claus). All traditions come from somewhere, the pagan ones probably had roots in somewhere else as well. Its gets better though, in Finland they adopted the day as "friends' day" so you would need to send a card to all of your friends! The post offices were happy.. and I guess people too.. I dunno.. for me it's carnival time and no Valentine's in here.
