A) Then, play started. It surprised us because it was really funny. When the actors asked for a volunteer l didn't put my hand up. But, yes, you guessed -they chose me!

B) We were travelling by coach to the theatre when our French teacher told us that the actors were going to ask for volunteers in the show. I love acting but I didn't want to be a volunteer because I'm not very good at French. I was worried that they were going to choose me.
C) In the end, I had a great time. Everybody in my class remembers the French play and they say I was the star. My French teacher is happy too!
