I'm a 'sweetheart'.
You're someone's sweetheart but you have a sweetheart of your own most likely. That someone is just in love with you. They may take Valentines Day to show you have much they do or are devoted to you. If you don't like them that way, (which is likely) still consider that they have to have a lot of courage to show you. Let them down easy but take something out of it. You must be a wonderful, sweet, caring, polite person if someone is that in love with you. With that personality, you'll find someone someday for sure.
