(G=Girl  B=Boy)

G: Hi, there. Where are you off to?

B: I'm going to the library. I'm revising for an English exam next week.

G: You've been working so hard. There shouldn't be any problem!

B: But I still need to brush up on some language points.

G: Come on, you'll be fine. You often surprise us with your amazing memory.

B: But I've been sleeping badly these past few days, and I just prefer to study alone in a quiet place so that I can concentrate and keep the details straight in my head.
