Input:  Person1:       Have you heard Jenny divorced her French husband ?  
 Person2:Oh , really ? No wonder that she looks quite depressed recently .  
 Person1:        Yes . They used to be joined at the hip .  
 Person2:I heard they were just married for half a year .  
 Person1:        That ’ s true . She said they often argued over nickel-and-dime things .  
 Person2:Yeah . Mixed marriage is tempting but full of culture shock .  
 Person1:        You said it . You know , they fell in love at the first sight and quickly jumped into marriage .  
 Person2:Maybe they were just attracted to each other but too different to be married .  
 Person1:        Definitely . Just hope Jenny can recover from the pain of divorce soon .
