Would you like to come to our party?
I'd like to. But I'm not myself today.
What happened? You look so pale.
It's the end of the world for me.
What makes you say that?
Today, I'm told I failed three courses.
Oh, that's too bad. Work harder next term.
B :: I'm such a fool that duplication of effort is only a waste time to me.
Don't lose heart. Everything will be fine.
I hope so.
