Why didn’t Mr. Plant continue his study after he finished school?

W: First of all, I’d like you to tell me a bit about what you’ve been doing.
M: Well, I left school after I’d done my A-levels.
W: What subjects did you take?
M: French, German and Art.
W: Art?
M: Well, I really wanted to study Art. But a friend of my father’s offered me a job-he’s an accountant in the city.
W: I see. In your application, you say that you only spent nine months with this firm of accountants. Why was that?
M: Well, to be quite honest, I didn’t like it so I got a place at the Art College a year ago.
W: Did your father mind?
M: Well, he was rather disappointed at first.  He’s an accountant too, you see.
W: Have you any brothers or sisters?
M: Two brothers, both at school. One’s eleven, the other’s fifteen taking his O-levels this year.
W: Right. What do you do in your spare time?
M: I like jazz and folk music; I go to the theater occasionally and act a bit myself. I read quite a lot, and I’ve done a bit of photography. Also, I’ve traveled a lot.
W: Very interesting, Mr. Plant. I think that’s all I wanted to ask about your background.
