Let's take a coffee break , shall we ?   I wish I could , but I can't .   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 .   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 .   I understand that , but you'd feel better if you took a break , even for just a short while .
