Cathleen: Let's take a coffee break, shall we?
Yolanda: I wish I could, but I can't.
Cathleen: What keeps you so busy? You've been sitting there for hours. You've got to walk around. You can't just stay on computer forever.
Yolanda: Well, I'm 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.
Cathleen: I understand that, but you'd feel better if you took a break, even for just a short while.
