Yeah, it's a Hallmark holiday, and yeah if you have someone in your life, you should celebrate them every single day, but heck, it's worth it just to see my wife's eyes light up when I bring her roses or chocolates or a card.
If you're with someone, not with someone, or with someone you hate, make the most out of the day and remember love. It's the sappiest of all emotions.
I love you, Kat. Forever and ever. You are soooooooooo stuck with me!
