Valentine’s Day is not a real holiday. Just the bastardization of a saints day to make money off of those stupid cards.
I happen to think Love between a husband and wife is worthy of setting aside a day to honor each other. Yes, we honor each other every day, but life gets busy, and it's nice to have a day where we, as a society, take some time out and show appreciation for our better halves.
And it doesn't have to cost a dime. There've been lots of lean years where I wrote my wife a nice little note and she baked me some heart shaped chicken with a heart shaped cupcake for dessert.
And if you're not taking time out to honor your spouse on this special day set aside to do just that, well, I'm sorry for both you and your spouse.
