In Act Three, Robbie's friends are disappointed because Alexandra can't come to the party.
Millie: Did she say why she had to leave today?
Mike: She told Robbie that her flight tomorrow was canceled, so she had to take an earlier flight today.
They are afraid that Robbie will be disappointed too.
Sandra: Do you think we should take down the decorations? They'll just make him sad.
Mike: Too late now. We should have done it sooner.
When Robbie returns from the airport, he does seem upset.
Mike: How'd it go?
Robbie: OK, I guess.
Will Robbie see Alexandra again?
