Funny how all this changes with the seasons of our lives. DH and I used to go out for Valentine's regardless of the day it fell on, but the last two years since DD19 isn't home, we've opted to stay home and cook steaks and baked potatoes. No dessert as we are so full from the meal.
I used to decorate when the kids were home, but not so much now. And, I would send them something to school. It's a big thing here. Now, I just get DGSs a small treat of some kind and take it to them after school. DH always gets me several things...card, chocolate, and flowers. He just can't resist, even though I tell him to not do it. I get him a card and make supper. I have to confess that I'm terrible at buying for him for Valentine's. It just seems to be upon me before I realize it's time for it.
