Well, Faulkland's really getting on my nerves. When Julia was good enough to forgive his awful behavior in Act III, he complains to Jack, "don't you think there is something forward, something indelicate, in this haste to forgive?" I know that if I were Julia, I wouldn't.
Jack is completely right when he says that Faulkland doesn't deserve her and that he "has no difficulties but of his own creating." When he tells him, "I have not patience to listen to you! Thou'rt incorrigible!" all I can say is amen!
There is certainly "something forward, something indelicate" in Faulkland's utter dissatisfaction and insecurity. If Julia were a friend of mine, I'd tell her to run like the wind!
What is his problem? ;-p
