I think you all are right. I will tell her. Although to be honest, in the recesses of my brain I am hopeful that it will cause a small tinge of guilt in her if she decides to come up by herself a day later than everybody else. I am also pretty sure that I don't want to be spiteful, and she would probably find out that I already knew and then I would prove to her that she is right and that I am a jerk and teh bane of all that is good. (just kidding a little about that last part)
