Yes, I opted for the obvious to wish all of you a Happy Valentine's Day!
As writers, we do a lot of research - or we should. I happen to like research and I looked up Saint Valentine. If you're interested, check out the ancient Roman who somehow has come to
represent the romantic holiday. Romance novels are big sellers, but even if you don't write in that genre, you might need a love scene or romantic interlude in your story. Let your imagination blossom. And, as i always say, Hit those keys!
