Pedro : How much longer are you staying in England,Olaf?
Olaf : Well, I don't quite know, but I shall be here for another year at any rate, probably two years.
Pedro : That's good. I shall be here for at least another year.
Olaf : What are you going to do when you leave Mr.Priestley's?
Pedro : I want to go to Cambridge. I discussed all this with my father before I left home and he said that he wanted me to spend a year in Paris and a year in Germany so that I could get a really good knowledge of French and German. Then he wanted me to spend two or three years with Mr. Priestley and try for an English degree at Cambridge.
Olaf : Have you enjoyed your stay in England?
Pedro : Oh, yes very much. I knew it would be pleasant but I didn't think I should meet such interesting people. But what are you going to do when you leave England?
Olaf : I am going into my father's business, a shipping company.
Pedro : That will be very interesting.
Olaf : Yes, I think so. At first I didn't think it woukd and I wanted something quite different. I thought life in an office was very dull.
Pedro : What did you want to do?
Olaf : I wanted to be an artist and paint pictures. I said that nothing would ever make me go into an office. " The only life for me," I said, " is a life of art. In a few years I shall earn flame and fortune by my pictures." Of course I was only fifteen or sixteen and hadn't much sense.
