Well, Valentines day really means nothing to me. It's a great time to get conversation hearts, but really, if they need a day to remind people to be romantic once a year, well that is just sad.
My husband and I spend time together, we go out to eat, hang in the hot tub drinking wine, etc all the time. I never really needed a day for stores to tell us that we need to spend money on jewelry we normally would not have bought because I don't wear the jewelry I have, or Godiva chocolates (ewww)....
I have been with my husband 17 years this year. I think we do just fine.
