[EX Q]: Person1: Do you remember Tina , my good friend ?
Person2:Yes .
Person1: She just broke up with her boyfriend .
Person2:Well , that happens . I hope she is all right .
Person1: But the problem is she and her ex-boyfriend are working in the same department . It is somehow embarrassing for them to see each other everyday .
Person2:That is the down side of an office romance . I hope their work is not affected by the emotional stress . The boss must be very annoyed if that will be the case .
