The Nutcracker was a magic story about toys coming to life. However, the play you were about to be in contained a lot of dancing as well when you read that the back of the script had a ballet manual on what moves to do. You didn't expect your theater teacher to include this in the script you were given actually.
There is however a problem with the school play you were going to be in, two actually. It was around Christmas time yes, but you couldn't dance, and didn't know anything about the nutcracker story other than the fact that it was a ballet. Hopefully the script you were given would help you get to know it. Another thing about the play you were going to be in is that your theater teacher hasn't given you a role yet, so you could be a bit worried of what you were going to play as.
