Group piano lesson

My daughter is going to have a group piano lesson tomorrow afternoon at her teacher's house. I am kind of getting nervous. Well, she will be performing in front of kids around her age for the first time. She has been practicing her song very hard for all this week but I don't know. I hope she does not get too nervous. I just want her to enjoy what she loves to do. She is excited the fact that she gets to meet other piano students and looking forward to her group lesson tomorrow.
