Why do you have a long face?
왜 뚱한 얼굴이야?

John: May， why do you have a long face?
May : Do you remember the seminar I mentioned the other day?
John : You mean the one about new market strategy or something? You said it was supposed to be in New York next week， right?
May : That's right. I really wanted to go， but Julia was given the chance.
John : Well， good for her. You can go some other time.
May : But it would have been a great thing for me if I could have gone. I know it's just sour grapes， but she doesn't know anything about marketing or New York.
John : Come on， May. I know you must be very disappointed but there will be another opportunity for you.
May : You're right. I'm just being jealous.
