Valentine Cards Make Me Happy

Valentine's Day cards make me happy. I have fond memories of Valentine's Day in elementary school. We made little mail boxes and kids passed out valentine's cards to everyone in the class. I would study any card that had anything more than a signature on it. What did that mean??! The way Jason wrote his name in cursive? Did that mean he liked me?
These are the kinds of cards I remember receiving:

This one is a little vintage, but I thought it was cute.

I was really into these Sour Hearts by Willy Wonka. They were only out for Valentine's Day, raising their value!
