>>10 I'm so happy you decided to do it! I'm sure it will mean the world to her.

If she knows what you look like, and you talk on the phone daily, there isn't too much to worry about. Obviously tell her "I'm feeling a bit nervous/shy..." and she'll probably try to help you out.

Maybe come up with a code/phrase/gesture between the two of you so that if the crowd does get to be too much and you have to go, she can know it's not her?

Either way, you have our support, so go forth knowing that!
