Are you all right, Mark? Is anything wrong?
I'm so homesick, I could die. All this studying, all this pressure, I just can't stand it.
It takes time to get used to all this.
Yes. But, you know, I lost sleep last night.
It seems like you've really got the blues. Have you heard from home recently?
It's been almost a month since I got a letter from my mum. I'm going to write to her and explain the situation. By the way, do you have an envelope that I can borrow?
Sorry, I don't have any. I hardly ever send any letters.
The bookstore is closed today. Is there another place I can get some stamps?
