Send her a IM or an e-mail would be better. Tell her, thanks for the e-mail, that it was a cute story.
At least acknowledged that you got it. C is trying to keep a small part of you in her life. Be nice tell her thanks. Your rewards may be great if you do.
I don't know why she sent it to you. Who knows. Only she does. It may mean nothing, it may mean something. Go with the flow. And quit shutting the door, LOL.
