Input:  Person1:       Good afternoon . What can I help you with today ?  
 Person2:I have a Time Deposit here and I'd like to get the money now .  
 Person1:        The maturity date isn't for another 10 weeks . Are you aware of that ?  
 Person2:Yes , I know , but I need the money urgently for a family emergency , you see . I know I should apply in writing if I wish to withdraw , but I'm afraid there just isn't time .  
 Person1:        The regulations state that the interest is paid at the rate of a Current Deposit , so unfortunately you will lose some interest .  
 Person2:Well , it can't be helped . I really must have that money . Thank you .
