A: Let's take a coffee break, shall we?

B: I wish I could, but I can't.

A: What keeps you so busy? You've been sitting there for hours. You've got to walk around.You just can't stay on the computer forever.

B: Well, I am up to my neck in work. I've got to finish this report. Sarah needs it by noon. I don't want to be scolded if I can’t finish my work by the deadline.

A: I understand that, but you'd feel better if you took a break, even for just a short while.
