Depending on how old you are. If you are between the ages of 10 - 15, it might be best to simply hand her a gift, cash, a stuffed bear, choclates, etc.. and ask her out. As long as it's on valentines day, she should say yes, and fall for you. Or, you could go up on stage at your school audotorium at lunch and propose to her through the mic, THAT would make her fall in love for life.I don't see why you're bothering though. I'd only say I love a girl on 1 day. April Fool's. I'm going bachleor for life!
