What was the woman’s problem?

M: Hi, how’s your writing?
W: I haven’t finished yet. I had trouble getting past the beginning.
M: How come?
W: Well, I was really happy to be writing a detective story. But after the first few pages, I sort of froze up mentally. I just couldn’t write any more.
M: The same thing happened to me. I thought it meant I lack imagination. Did you ask Prof. Wilson for help?
W: Actually, I went to ask for more time to finish the assignment But instead she gave me some advice about how to keep from getting stalled in my writing like that, She said that the first thing I should do is just write anything that comes into my head even if it doesn’t make sense, sort of burble warm up exercise.
M: That’s interesting.
W: Her methods seem to have worked for me. I should be able to hand it in on time. But first I need to go to the jewelry store.
M: You are going shopping?
W: I’m going there for my story. My detective solves a jewelry store robbery. So I want to take a look at how jewelry cases are arranged, where the security cameras are located, that sort of thing.
