She is really excited to be going. Well, until you respond, she doesn't know if she really is going. Can you please answer the PM with your Number so she can call you, or call her on her cell. If it is a prank or a joke can you let me know ASAP, so I can let her know the truth, that it is a lie.
Really not a cool thing to do, if it is a prank/joke, etc.
