M: I just can’t concentrate here in the flat. (19)You see, Arthur, I’ve got three essays to do... three essays behind I am. I mean... (20)how can I concentrate with everyone else talking... playing records... practicing the guitar? I just can’t get pen to paper.
W: Well, Peter, you could work in the university library.
M: I could... yes... that’s perfectly true. But... you know... I not only need to (21)sit down and write... I... I... need to think.

Well there are constant interruptions you see. You’re okay... you live in... Don’t you believe it’s as ideal as it seems. I mean people call on you at all hours... to borrow a book... have a chat... find something to eat... No... it’s anything but ideal for a quiet life.

W: You might find something under the headings.
M: Yeah. Here we are.
