Dear John,

I'm sorry you didn't get the part you tried out for in that play. I know how much you wanted to be in the play. Now you feel that maybe acting isn't the right future for you. I think you're wrong. You're a good actor. Do you remember when you played Caesar in your summer theatre group's play? You were excellent . People clapped(鼓掌)every time you walked on stage（舞台). Even the other actors loved you.

All actors have to get used to being turned down for a job. It's part of an actor's life. Even famouse actors don't get every part they want. I think you should give acting another chance. You love it so much, and you're good at it. Don't be discouraged because you lose one part in the play. Wait a bit, and try for another one. After all , you can always give up some other time.

Love,

Jane
