I helped a friend decorate a cake last night. It was my first time actually decorating one. She posted a picture of it on a social networking site when it was done, but she didn't mention anything about me helping her with it. People have been commenting her picture saying how cool it is and everything, and she hasn't said a word about having help with it. I think this has something to do with a grudge. I don't really know what it is.

I don't know what's making me sicker: The cake or the fact that she's taking all of the credit for something I helped her with.

What should I say to her?
