Scene 2
JAMIE: Mom, Dad, I need to tell you something. (Looks nervously at his parents.)
MR. JACKSON: Why do you look so tense Jamie?
JAMIE: I got a scholarship to study law at Yale University. I know you both wanted me to pursue drama, but I've always been interested in law.
MRS. JACKSON: Jamie this is fantastic! We are very proud of you. What you want to make of your life is more important to us than what we want.
MR. JACKSON: Hearty congratulations to you, my boy. (Smiles widely at Jamie.)
JAMIE: Thank you so much. (Takes a sigh of relief and smiles back at his parents.)
