Who cares if it was a pagan holiday 9 zillion years ago. It's called Valentine's day in the 21st century.
I'm going to spend time with my honey. I don't care about gifts, flowers, chocolates, or cards, though he'll probably give me all of the above because that's his way of expressing love (especially if he writes poetry in the card). I just want to spend time with him alone. We love each other and do a lot of things together, but it's always nice to remember a special day of love in the middle of the busy-ness of life.
