In Act One, Robbie is thinking about Alexandra and their friendship.
Robbie: She's a terrific person. I'm going to miss her when she goes back to Greece.
Ellen suggests having a special party for Alexandra.
Ellen: Would you like to give her a little farewell party?
Robbie: Mom, that would be terrific!
And Robbie would like to buy Alexandra a gift.
Robbie: I'd like to give her a nice going-away present.
Ellen: Fine.
Robbie: There's only one problem.
What's the problem?
